C64 Emulator Bugs
after stumbling about a bunch of VICE bugs myself in the last couple of days i have decided to compile a list with issues current emulators have. the goals for this are
- make people aware that emulators are by far not perfect (yet?)
- make it easier for emulator authors to improve the emulators, by showing problematic programs and possibly provide simple testcases
- allow c64 coders to implement emulator detection if desired
so well, check this: http://hitmen.c02.at/files/docs/c64/c64_emulator_bugs.txt
help welcomed :)

The bug which happens when switching back and forth between vice and other windows happens on windows 2000 and XP also. (both pro)
serial timing latency is not implemented. (1 cycle per foot of cable or so).
1571 has extra delay on on reading sync inside the drive, ask graham or krill about this. (you cannot use BVC in 2mhz mode!)
clk has one cycle extra delay or so also in 1541 when data also changes... (or something)
NTSC should have at LEAST 8 more lines visible in bottom border, and about 6 or 7 in the top.
palette is still very wrong, look at hoxs64 for proper palette.
CAN YOU PLEASE emulate a breadbox palette seperate from 64C pallette, 64c palette is UGLY as hell on OLD games!
I will post more as I remember them...
1541 emulation needs complete REWRITE, it does NOT work with most protected games, HELLO , NOT ALL DATA IS GCR ENCODED!!!
(Stop letting lamers like rittwage who got not CLUE how 1541 really works writing code!!!)
if you want a REAL book on 1541, see 1541 SAMS trouble shooting an repair guide, it contains FULL HW explainations!
You can also switch OFF byte sync in the 1541!!!

Groepaz, Fungus & I talked about this on IRC yesterday, so I'm not sure if the bug I found has been 'documented' already...
Toggling RAM/ROM quickly (i.e. changing value of $01 between #$35 and #$37) confuses WinVICE to the point where it doesn't seem to know whether it's RAM or ROM you want.
Also in WinVICE, "always on top" doesn't work when swiched on at boot. Frankly, I'm amazed that this isn't the 'known bugs' list already. |

Also that friggin' annoying bug that un-toggles True Drive Emulation everytime I load a .prg really pisses me off too.
Not a real emulation issue but it's out of my system now :) |

I always make a copy of the x64.exe file and name it x64prg.exe.
Then I couple .prg files to x64prg.exe while coupling .d64 to the normal x64.exe. :) |

I just enter the monitor and type l"program.prg"0, and then everything works fine without having to change drive emulation settings etc.
The problem with the complete border not being visible is well known and something the VICE team doesn't seem to care too much about fixing. Krill's border patches take care of that on PAL; should be easy to modify them to fix NTSC emulation as well.
Fungus: You do know you can change the VICE palette yourself, including toggling between the two luminance settings, right? :-P |

From groepaz's buglist.
Not a bug:
*** [vice 1.21] audio/video timing problems due to audio buffering
Audio buffering is a requirement for any software based audio playback. The option is there to set the buffer to a lower value for those with fast machines, which makes the problem less apparent. Impossible to work around. |

still there is no option to set it below 100msec. And that's still quite a lot! why not allow 50msec? or 20msec (== 1 frame). My pc wouldnt be bothered by it. |

For windows there are ASIO or WDM drivers for many soundcards that will allow near realtime audio (a couple of milliseconds or less in latency).
A selectable buffered video to match the lag of the audio could be useful for watching timed demos.

Simply delay the video update to be in sync with the audio...
radiantx : I certainly don't want to sit here for hours and hours and hours tweaking the palette to make it look right, this is NOT my job!
missing thing in the emulation, is CRT phosphor emulation also.

From a graphic-artist's point of view, i'd say the vice anex pepto palet is fine.
furthermore, if there are things missing, why not create them yourself??? |

as for the palette i have to agree with hein - enable the pal emulation and then tweak it to your taste. this is pretty much the same as adjusting the image with the knobs at your monitor - and its NOT the job of the guy who sells you the monitor to tweak it to your liking :=)
however, stick to the topic please =) and read the damned textfile i linked to before posting stuff that is already in there =P |

Groepaz, this is a brilliant idea - I aimed to put together a similar list a long time ago, I just haven't come across that many examples of inaccuracies to justify it.
However, I reckon that it's not necessarily a step in right direction to focus strictly on VICE. New versions are very sparse nowadays, and they primarily include new features rather than fixes to the core emulation. It just seems that it's versatility that is the main goal for VICE, not perfect accuracy in all instances. I reported a couple of bugs to the developers, but none of them have been fixed. I sent a mail to the devel-list with a bug report, and they couldn't be bothered to acknowledge it. Well, if they don't care, why should I. It is not my intention to blame anyone, I grasp the fact that every-day occupations don't always allow to spend hours on a C64 emulator. However, I'm afraid that with no new people contributing to the development of this emulator, the list will just be getting longer and longer.
The only emulator seeing a rapid progress these days is Hoxs64, and I think the time and effort would better be spent looking for flaws in this one. It has its downsides, namely no support for MOS6581 and NTSC, but it does an excellent job at emulating 8580 equipped PAL machines. Most importantly though, seeing as the emerging bugs actually get fixed, the list wouldn't go in vain.
@Fungus: In VICE, go to Settings/Video settings/VICII Palette, select "External Palette" and choose "vice" from the list - it is the one calculated by Pepto, which is also used in Hoxs64. |

that list is NOT ment to only focus on vice. its just that
a) my main desktop is a linux box, so i am using vice most of the time
b) vice seems to have the most bugs :) many of the problematic programs in the list work fine in ccs for example
so yes, ANY emulator bugs/problems are subject to be described in this list (that is, stick to CCS, VICE and HOXS ... i dont think any other emus can compete yet)
as for vice team not acknowledging bugs - yes indeed. many have had that experience. this is one of the reasons for compiling that list - i believe that providing (a lot of) examples of malfunctioning programs, including some guesses on whats the cause, could indeed motivate either current vice developers or whoever else to fix some of them. *ignoring* them certainly does _not_ help anyone :=)
so if you can tell further problems that aren't in the list yet, go ahead :) |

Vice 1.20+, Elven warrior: during game does not display in PAL. Works in NTSC mode. It's one of the bugs I noticed in Hoxs64 too, and David fixed it promply few days after, like every bug reports I sent him from version 1.0.4.16 :)
Quoting from Hoxs64 history:
3) Adjustment to the VIC display enable bit. The game Elven Warrior now displays. |

"The IFFL scanner sometimes hangs when you flip 1541 disks in VICE"
Please note that I have not done extensive testing on real hardware. I've never experienced a hang on real hardware, but while I have tested in VICE hundreds of times, I've only tested on real 1541s a dozen or so times. However, I've never managed to reproduce the bug while I have breakpoints set in VICE, which is mysterious...

The entries to be removed:
- [vice] Zamzara/RSI Zamzara +CH
A: It shows the same behaviour on a real thing, so it's not a bug in the emulator.
- [vice] Lifeboat/Dover Dodge Lifeboat
"crashes on both VICE/CCS after pressing the key..."
A: Corrupt, it doesn't work on a real C64 either.
- [vice] Violator +4/X-Ray Violator +4
"Not working in VICE, No option now to test it on real c64"
A: The same behaviour on a real thing.
- [vice] Skate Crazy/Shining 8 Skate Crazy
second part crashes in vice, works in ccs
A: It's already fixed, works in VICE v1.21.
To be corrected:
- [vice] Comic Art 9/Mayhem Comic Art 09
Main file crashes in Vice 1.19/1.20, works in CCS64 V3.0 Beta 1.7
A: As a matter of fact, it's CCS64 that's inaccurate in this case - the collection crashes on a real C64 in the same way as in VICE and Hoxs64. |

A couple more to get rid of:
- [vice] Coop/Spench, The Sixth Sense Coop
"Not working in VICE or CCS64", crashes shortly after run in vice 1.20
A: Doesn't work on a real thing either.
- [vice] Compressor V1/AFL Compressor V1
crashes after intro (syntax error?)
A: The same error on a real thing - not an emulator issue.
- [vice 1.20] The Movie Writer V1.2 The Movie Writer V1.2
"directory routine doesn't seem to work in vice1.20"
A: Neither does it on a real C64. |

I noticed that *randomly works* on all 3 emulators, just wait some seconds before running and it will eventually work. It's a problem of this release only, a simple lda #$7f sta $dc0d, that SHOULD be there to properly init the irq, will fix it.
load but don't run, enter monitor
break 819
x
then after run:
> dc0d 7f
x
will work.
Part one properly sets $dc0d in the intro and seems enough.
Another one that did not work in any emu is this
Die Donnernde Kataun/Abyss
Die Donnernde Kataun
irq does not trigger correctly.
Patching it like this will do:
0873 20 D4 08 JSR $08D4
08D4 8D 1A D0 STA $D01A
08D7 8D 19 D0 STA $D019
08DA A9 1B LDA #$1B
08DC 8D 11 D0 STA $D011
08DF 60 RTS

Ah now I see that it randomly refuses to work, also in Hoxs64. Did you check whether this randomness occurs on the C64? I've already disconnected the C64 setup and don't feel like reconnecting it today. :-) |

sta $d019
lda #$80
sta $d012

sta $d011
lda $d019
and #$01
beq *-5
such code as this will work on a real NTSC c64.
such code as this will fail on a real PAL c64 intermittently.
see Waterline by publisher Tronix (and don't ask me for link, go search gamebase yourself ya damn lazy gits)
similar strange issue as this on the Galactic Gardner, the irq setup in the bottom border happens TWICE in row (although can't seem to find a reason WHY) on a real C64, PAL or NTSC. IRQ happens ONCE only in vice. (Very annoying when trying track down such bugs.)

fungus: thanks but, you gotta realize that to a decent bugreport belongs a link to the specific program that causes a problem. just naming a game is NOT very useful.
anyway, i updated the list with the info posted so far -> http://hitmen.c02.at/files/docs/c64/c64_emulator_bugs.txt

When stating that it crashes on the real thing you should probably state which real thing you used.
There are some minor differences, the kernal revision is one example.
Some very old programs can sometimes rely on strange behaviour.
If you say something like C64C ~1989 or breadbox ~83 it will help. |

Actually not an emu issue but it's only a fault on the cruncher used, which expects all the mem filled with zeroes(!!)
Fill the memory with zeroes yourself, or set the memory fill pattern to all zeroes and it will work everywhere. Easy to patch :)
In CCS works because the mem fill pattern is REVERSED (00 instead of ff and viceversa). Fill the mem with ff's and you'll see it failing on ccs too. |

So to sum it up - the crash is not an emu issue, but the fact it doesn't crash in CCS64 actually relates to an emu issue. :) It should fail, provided you don't change the memory pattern.
Quoting tlrIf you say something like C64C ~1989 or breadbox ~83 it will help.
All of the tests I've performed were carried out on the C64C with serial number 774125.
Here's some more verified entries:
- [vice 1.20] Aurora 90%/Level64 Aurora 85%-90%
"On emus, there will appear a strangely-patterned screen. Get yourself the real
thing or expect major vic-bugs after pressing run/stop."
"btw, aurora80% displays same on emu then on realthing, i just did that emucheck
for the fun of it, its temperature measuring via unused bits in $01"
A: This one's interesting. First of all, in both the 85% and the 90% versions, I've spotted no VIC bugs - neither in VICE nor in Hoxs64. Secondly, that strangely patterned screen is visible on a C64 as well, but it disappears after a while. In emus, a user interaction is required to proceed, and this seems to be the only difference. This affects CCS64, VICE, and Hoxs64. I've reported it to David Horrocks, the developer of Hoxs64.
- [vice 1.20] Locomotion +2/Hitmen Locomotion +2 [german] (works in ccs and on real c64)
A: It doesn't work in Hoxs64 either, which has been reported to the author. I can confirm it works on the C64 (at least all of the attempts to run the game were successful).
- [vice 1.20] Rick Dangerous/Myth Rick Dangerous (works in ccs and on real c64)
A: It doesn't work on the real thing, which was confirmed by j0x in the comments ("I did this because I was curious why it didn't always work under Vice - or on the real thing, for that matter"). Again, the fact it does work flawlessly in CCS64 suggests that an inaccuracy exists in this emulator.
- [vice] Demo IV Demo IV
the last part flickers
A: And so it does on the real thing, however the flickers are much less frequent and perfectly predictable. They occur 3 times per tune duration - at the very beginning, then 8 seconds into the tune, and the third one occurs when the melody sees a rapid change. In VICE, the flickers are very frequent and they cause the tune to restart at times. This part doesn't work at all in Hoxs64.
- [vice 1.20] Leftovers/Shadi Software Leftovers
"The intro part has light blue background where it should be black. (atleast in VICE)"
A: It's light blue in Hoxs64, CCS64, and on the real thing. Looks to me like a bug in the code or a bad visual taste. |

This is probably a kernal revision issue. One of the things that differ is the color in colorram after printing a #147 (CLR).
IIRC the different behaviours are:
- colorram set to 1 (white)
- colorram set to the contents of $d021
- colorram set to the contents of 646 (i.e cursor color)
A lot of older demos relied on the two last of these. |

@Fungus & others: Correct me if im wrong.
(I'm running vice 1.21)
Here on my real ntsc c64 the right border has 8 more pixels to display raster colors and siderborder sprites.
PAL Vice emulation displays 384 pixels width.
So, correct NTSC vice emulation would be 392 pixels width.
The reason for the extra 8 pixels is ntsc being 65 cycles ?
One more thing : The $d010 emulation in vice ntsc mode bugs.
Try watching my intros in vice ntsc mode:
http://intros.c64.org/inc_download.php?iid=2803
http://intros.c64.org/inc_download.php?iid=2047
http://noname.c64.org/csdb/release/download.php?id=56326
Left side siderborder sprites are off 8 pixels
They work fine on a real ntsc ..
Thats it for now. :---)

It crossed my mind it'd be a wicked cool feature to have all emu-detection routines (what I mean here is the routines with a deliberate purpose of detecting an emulator - separate or included in specific productions) listed in a table with the holy trinity of CCS64, VICE and Hoxs64. It'd indicate whether the emulator is capable of fooling the routine into thinking it's running on the real thing. To spare you some work, I've prepared one. The tests are sorted by date, you're welcome to add anything I'm not aware of.
Y - test passed, N - emu detected
CCS64 VICE Hoxs64
Deus Ex Machina Y Y Y
Demus Interruptus Y Y Y
+h Emu-Fuxx0r v1 N N Y
+h Emu-Fuxx0r v2 N N Y
Waveform Composer Y N Y
Aurora 90% N N N
Krestage 3 N N Y
valid for: CCS64 v3.2, VICE v1.21, Hoxs64 v1.0.4.23

Tape and t64 are 2 different things, a t46 is just a collection of prgs with a header, and vice loads prgs directly in memory bypassing normal tape routines; tap files are what you need to see "those red lines", if you mean tape loaders by it :) And you don't have to disable TDE to load taps, normally. Some protected games check if there's a drive attached and refuse to work, btw. |

It is possible to load the parts separately. The part after the "Really nice picture (FLI) of a red car" won't work if you start the demo from the very beginning, or "0A", or "0B". It will work, however, provided you start the demo from the "0C" file (which is the part preceding the troublesome one) or load the part directly ("0D"). The same quirk occurs on the real thing.
As for the "Restire" key failing to work in the part 0H, it does work if you press any other key beforehand. For instance, press space and "Page Up" (Restore) subsequently to exit the part. This is how it works on the real thing too - the problem lies in the code, not in the emulation. |

"This demo won't run with CCS as it cannot handle DreamLoad's ShutUp-Feature. Then, I don't
think any emu up to now can play the digi-part in original quality."
"A: The demo works in CCS64 v3.3, so it must have been fixed at some point."
The above belongs to "EMULATOR ISSUES THAT HAVE BEEN FIXED", I think. Append Hoxs64 to the list of emulators that can't handle Demo IV properly (it crashes on the last part unlike the real C64). What's wrong with Crazy News preview?
I see that you've included the emucheck list of mine, but it's already outdated. :) Here's the latest, including Cucumber Juice 2 for the sake of completeness, and reflecting emulation improvements in CCS64 v3.3:
Y - test passed, N - emu detected

"does not work on CCS nor Vice - works on the real thing"
I can only wonder how it was verified to work on the real thing. In order to make it work in CCS/VICE, make use of the hint in the directory, which says: "rest on side two". Amazingly, the rest is on the side B on the real thing too. ;D |

I've been made aware of a significant CCS64 flaw. Namely it comes packaged with Kernal Revision 2. However iAN CooG claimed to have checked "Leftovers/Shadi Software" with Kernal Rev2 in CCS64 and wrote here that the intro part was all black, while it's blue with the Kernal that CCS64 comes with. Could it be that there are different Rev2 Kernals around?
I found out that "Rick Dangerous/Myth" fails in CCS64 v3.3 with Kernal copied from Hoxs64, which suggests that it's merely a Kernal revision issue. It should be noted that the game works solely with Kernal Rev2 and will fail in any emulator using Kernal Rev3.
Yet another emulator that can't handle Demo IV properly: CCS64. Flickers madly and the music is prone to restarting. Which means that for the time being there's no emulator that would display this part accurately. |

CCS always has a PATCHED rev2, which load $0286 instead of $d021 during jsr $e544. An ugly hybrid I never understood why not simply replace it with a rev3.
I tried with a real rev2, I have something like 40 different kernal roms in CCS\ROMS\ dir to make tests with ;) |

SounDemons noise waveform hacks does not work in emus too, since they don't emulate the aspect of the SID used here (was the intro/demo called "pica" or something like that?). |

"Pico". Granted, CCS64 and VICE can't playback the waveforms as intended (although the former passes the emulator check in Waveform Composer), but did you check with Hoxs64? Numerous fixes were made to it in the past to ensure that these waveforms are handled properly.

A new version of Hoxs64 has been released, it can now handle the following titles:
-Aurora 90% ($01 fading corrected, passes the emu check, there's no need to press run/stop to proceed at the beginning anymore)
-Locomotion/Hitmen (IRQ timing adjusted, works now)
-Demo IV (it doesn't crash anymore and flickers in the same manner my C64C does)
The updated emu check list:
Y - test passed, N - emu detected
CCS VICE Hoxs64
Cucumber Juice 2 Y Y Y
Deus Ex Machina Y Y Y
Demus Interruptus Y Y Y
+h Emu-Fuxx0r v1 N N Y
+h Emu-Fuxx0r v2 Y N Y

Aurora 90% N N Y
Krestage 3 Y N Y
valid for: CCS64 v3.3, VICE v1.21, Hoxs64 v1.0.4.24
Ipso facto, Hoxs64 becomes the first C64 emulator to be undetectable by any emu check known to date. \o/ |

Is it fair to use the 1541 as EMU faxxor? It's very simple to set up some drive code that would rely on the analogue properties of the serial cable, which would be tricky to emulate. It's all a very simple test which I implemented some years ago. Simply generate a square waveform from the drive to the C64 in f.e. 1KHz. Sample this waveform on the C64 in a much higher frequency. In a pure digital world (Emulator) you would count equally many zeros as ones but in the real world this number will differ greatly due to the CMOS logic levels and charge times.
Anyways, requiring a 1541 for EMU-detection is a bit cheaty imo. ;D |

It's also dangerous, because different drives might behave different. There's also 1541 compatible non-Commodore drives. |

Agreed, but thing is that on an emulator the ratio is EXACTLY 50/50 but on the real thing it'll never be like that. |

"*** [vice 1.21] strange issues with $01
seems that switching $01 quickly makes VICE make mistakes in thinking what is RAM and what is ROM...
Interestingly, this one fucks up in WinVICE v1.20 at max. speed and warp mode, but not @ 100% speed.
Brings up (a seemingly long-time known bug) that toggling RAM/ROM quickly (init tune at $E000) confuses VICE.

Well spotted, the glitch is visible in Hoxs64 too. CCS64 v3.3 isn't affected by this.
Quote:the Aurora check in principle is pretty analogous as well. Didnt think it would 'fall' so soon actually :) and I doubt it's beaten yet. The behaviour of those unused bits is correlated to chip-temperature as yago pointed out :)
This one's beaten to death. :) You could measure the fading time multiple times and then check if the values differ, but you can't possibly verify if even values indicate a coincidence or an emulator. And even if you could, it should pose no challenge to randomize the values in some specified range. More attempts to exploit this (or any other oddity that isn't emulated exactly) would be quite useful though. Something along the lines of "detect Hoxs64 compo" should be organized to promote this kind of art. ;) |

I think randomness is an issue but probably only exploited 'at will' and not randomly :)
Here's a small code that should detect all emus so far I think. However it is VERY simple to circumvent detection here - nontheless:
tmp = $02
adr = $31
ldy #$00
sty tmp
ldx #$60
loop
lda (adr),y
eor tmp
sta tmp
inc adr
bne loop
inc adr+1
dex
bne loop
lda tmp
beq emu
rts
emu
inc $d020
end bvc end
Edit: dont mind $31. Just some arbitrary memory range to EOR over. So $00 or $00,$FF -filled memory pattern would expose an emu (or memory configured AR i.e.!) |

Relax #3 often crashes, but randomly works.
I don't understand why it should work, and actually it should NEVER work IMHO.
The irq init is completely f**ked up, and prone to lock-ups or crashes.

0833 8E 1A D0 STX $D01A ;Set to 0 and will be never set to 1 (=no irq?)
Even in Hoxs64 1.0.4.24 sometimes locks up.
Works on Vice without TDE active, or simply loading the .prg alone.
I think this is a side effect of inaccurate emulation when TDE is off.
Here's a quick fix, there is enough room for a (almost) correct init.

Thanks for the update. It would be clearer though if you had added "Works properly in Hoxs64 v1.0.4.24+" to Aurora 90%, Demo IV and Locomotion, because right now there are statements like "This part doesn't work at all in Hoxs64" accompanying these entries while they aren't valid anymore.
Remove Skate Crazy/Shining8 as it's already on the list in the "EMULATOR ISSUES THAT HAVE BEEN FIXED" section.

Almost the same issue as in Comic Art #9/Mayhem, decruncher relies on memory
contents and most probably filesize ($ae/$af contents after loading).
Patch the main file adding 16 zeroes at end and it always works.
Actually both this and Comic Art 9 will run unpatched if you reset after the
crash and reload them.

IIRC Typical upscroller reads some $de00/$df00 byte every frame after calling the music routine, and if it gets the same byte back multiple times (16? 32?) it crashes the demo. I think some part which didn't work correctly with some cartridge, or maybe I did that just to piss people off :)

Those garbled red sprites should ring some bells :)
Sprites must be off before loading, else one should expect timing problems.
4E6C 20 4B 54 JSR $544B

547A A2 00 LDX #$00 <<< here does it right...

....
4E99 A9 7F LDA #$7F <<< and here turns 7 of them again on
4E9B 8D 15 D0 STA $D015 <<< just before the load (JSR $6100)
to fix it, during the second intro, enter in monitor:
> 4E9a 0
Actually it worked in Vice with any fast loader (AR/Epyx/KCS/Speeddos) that
allows sprites, setting them off automatically during load.

Failed on my C64C. It hangs up in CCS64 too if you boot it in the "Normal" (more accurate) mode. Which brings us to the conclusion that in this case the emulators are fine and the software is bugged. |

Did you test with any cartridge? What kind of C64 was it (C64, C64-II, C64C?) and which Kernal was it equipped with? Any expansions used?
The tests I've performed were carried out on a bare C64C (Kernal rev3) and a 1541-II disk drive. In case of a failure, I've always rechecked the title at least once to ensure that the behaviour doesn't vary. |

noticed another problem, check out Info Everybody. its using a "jam" opcode to halt execution. a real c64 would just freeze and show the screen, vice gives a "cpu jam" message, and does not show the proper screen ever. :(
as for the releases which worked on masons but not on assiduous' real c64.... maybe a 1541 (old) vs 1541-II (new) issue? |

Do you know how often I use that JAM for debugging purposes. When you have some more complex conditional code and want to make sure you've reached a particular point in the code I simply put a .byte 2 there in the code. If it JAMs then I reached that code. I also use it for timing, like after a stable IRQ I put a .byte 2, when VICE JAMs I check at which cycle the VIC is on (right there in the monitor). Since I know at which cycle I wanna stop on I simply apply the appropriate delay, instead of fiddeling with inc$d020/dec$d020 to find the correct cycle... |

The tests I've performed were carried out on a bare C64C (Kernal rev3) and a 1541-II disk drive. In case of a failure, I've always rechecked the title at least once to ensure that the behaviour doesn't vary.
I got the old UK model. Also got one of the old 1541 drives.
No expansion used |

Takes longer time because then I must first enter monitor-mode manually, then add the break point on an address I don't know. Hence, simply adding a .byte 2 and do "make run" is MUCH simpler. ;D
I do use break points of course as well but not for the purposes I wrote in the previous post. |

Actually, breakpoints seem to be buggy on vice. Maybe it was just me, but a "sometimes-working" breakpoint is completely useless.

Quote:as for the releases which worked on masons but not on assiduous' real c64.... maybe a 1541 (old) vs 1541-II (new) issue? Certainly not with Flying Shark and Dylan Dog - the former is a one-filer, the latter crashes prior to the trainer selector.
I don't know about Invest as it obviously crashes on loading, but I doubt it's a drive revision issue given that it fails in the very same manner with 1541 selected in VICE. Could it be that some error was introduced in the process of transferring the disk and Mason checked the original 5,25" floppy? |

I've put all them here, if you want them =)

Here's what I found debugging DylanDog/X-Factor.
IRQs are not properly stopped when intro starts, and while calling music init
at $E000 an irq triggers using vector at $FFFE (which points at $F000, hence
the crash)
to fix, before running:
break 2800
x
and then the usual missing one:
> dc0d 7f
x
and intro starts.
Too bad that even the end sequence loading will lead to a crash.
It should do a jsr $1031 to set $01 and other stuff before but doesn't.
fix:
break 1029
x
now press 4 keys N-I-C-O together, release and press LeftShift+Q
> 01 36
x
to make it load.

Someone modified the filenames adding trailing spaces, remove them and loader will be happy. It's true what the note says anyway, that turbo options crashes 2nd part loading (press ctrl to exit). |

Traced in vice monitor, never reaches the cli/jmp$4000 in the decruncher and memory is filled with garbage. Most probably a bad file. A single byte different leads always to this. Fails in hoxs64 too. |

Simple test for support of in-line graphic _data_ changes.
Check for horizontal splits.
Does not work in VICE 1.21 or CCS V3.2. Works in Hoxs V1.0.4.15.
Should probably set $d800 too, but I leave that as an exercise. :)

Another Vice bug I've found today (if no-one has discussed it):
Latch X and Y ($d013 and $d014) are not emulated properly on Vice.
I tested this by repeatedly printing their read values on the screen by every frame, alongside the values stored in $dc00 and $dc01 - as I wanted to test this after seeing a very nice raster stable routine in an old Crest demo.
On Vice, when you press and hold the space bar or any of the keys in the bottom row, the values in $d013 and $d014 only change once, where as on CCS64 and a REAL c64, they change every frame - which is of course what they SHOULD be doing on Vice.
Maybe this bug can be fixed for the next version?
EDIT: The stable routine by the way, was found in the mega split-raster part in Blow Job 5/Crest, I'm not too sure if it was either Crossbow or Vision who coded the routine. |

that way of doing stable raster was developed by hannes sommer and published in the 64er mag (just for the records :=P).

Quote:good find though, care to write a small testprog that shows the problem? :)
I just simply did this in AR monitor:
loop:
LDA $DC00 ; Keyboard write/Joyport 1
STA $0400 ;
LDA $DC01 ; Keyboard read/Joyport 2
STA $0401 ;
LDA $D013 ; Latch X
STA $0403 ;
LDA $D014 ; Latch Y
STA $0404
JMP loop
Doesn't matter how IRQ is setup etc. The effect relies on when you press various bottom row keys or hit fire button in Joyport 1. Try it on Vice and then the real machine and you'll see the difference.

New bug:

Works in earlier version and all the others. In 1.22 only a light blue screen.
Changing VIC-II settings/border doesn't produce differences.
The notefile works in normal and full borders mode, not in debug mode.

Quoting David Horrocks from comp.emulators.cbm:
Quote:
Hi Vice Team,
The demo H2K by Plush seems to have further degraded due to the sprite
emulation changes in this version. VICE v1.21 played better. The part that
is affected is the totally blue screen that slowly turns to a totally black
screen by way of an anticlockwise sweeping effect. This anticlockwise
sweeping effect appears immediately before the chessboard screen during disk
one. I have confirmed that the display is correct on a real C64C. CCSv3.0
has a comparable fault with the same effect which has been corrected in
CCSv3.3. I believe the problem lays with the logic that decides when to
start emptying the internal sprite shift registers out the display and/or
the logic that fills the internal sprite shift registers with data. Hope
this helps.
Regards
David
so:
[Vice 1.22] +H2K/Plush +H2K
Choose "Chessboard spin" in part requester, the anticlockwise wipe effect shows some dirty lines.
I have to add that the endscroller crashes just after the last japanese text. In Hoxs64 continues correctly. |

When I watched the part "undulation" (can be accessed via the shortcut and press fire, and then load undulation from the good old Crest demo, the Bubble Tale
I noticed that with the Vic II border set to Debug. It looks like crap. the sprites are bouncing of the rasterbar and everything is fucked.
with the Vic Ii border set to full, it is a bit more close to the original but there is a bug in the stretch routine which was not even there in vice 1.21 or displayed in c64.

Just want to let you know that we're working on fixing (some of) the bugs you're collecting here. Thanks for this list.
Current state of progress:
ElvenWarrior, Camelpark: Patch exist to fix the problem
Tsunami: Problem is identified, patch needs further investigation
+H2K (before chessboard): Problem is identified (sprite x positioning), got worse with the patch for Krestage 9 sprite feauture, needs more investigation.
The new VICII border modes were introduced by Krill but he oversaw that the borderwidth variable is used for some essetial calculation which needs to be fixed.
Bad luck that there were more bugs introduced with 1.22 release. Maybe we could find some beta testers before releasing next one.

Why don't you do a public beta, or a release candidate, a week or two before releasing the final? Doesn't have to be a full release, just win32 binary and source snapshot, so that people can download and test. |

Of course 1541-II has to be used, else you won't get to the end of side 2. Still crashes in vice 1.22, works on hoxs64 which uses a 1541-II rom. |

A bug I discovered in VICE when I coded on The Wild Bunch was that the timing when an NMI interrupts an IRQ setup was incorrect. IIRC it was 4 cycles too much in comparison to the real thing. All I remember was that I had to take special precautions to old CIA, new CIA and VICE CIA. I'll try setup a test case someday or if somebody else cares to look at it.

Disk-drive problem I've found in WinVice v1.22:
After receiving a copy of Krill's loader (version 22) for an upcoming project, the loader does not seem to be compatible in loading files under a 1541 or 1541-II disk drive attached (testing with ONE device attached as instructed)... on all other drives it works fine. The installation of the drive code works, but after execution command (M-E) the drive LED is on and drive itself seems to freeze. Krill said that the loader does work on HIS version of Vice, which is version 1.20 - so it seems it's a bug in version 1.22 (when drive LED enhancement was put in.)
Previous 2006 demos like "The Wild Bunch" and "Aurora 85%-90%" which use Krill's loader - all seem to work fine, but that may be because it's using an older version of the loader.
I then installed an older version of Vice (1.21) and tested the loader on that, and it worked perfectly.
I then checked all v1.22 ROMs stored in the DRIVE folder, but they are exactly the same as the ROMs in older versions, so it's not the ROMs that's causing this particular problem. |

maybe an idea, I don't know. a flag on the releases page to show which emulators don't run certain demos etc. Yes people comment on them, but it would might make it easier to just make a list of them quickly?
appart from the code falling over, a lot of packers/loaders would cause problems? so perhaps fixing them first within the emulator would help clear that list a lot.
do you fix the demo, or the emulator?!?!
although emu's do a good job on the whole =) |

in the file "tune-eater" (see http://scythoior.com/W0641A.D64) we had a logo that was flashing in sync to the music (iirc it was triggered by the 81-waveform on track 1). in vice it flashes much too often, there must be something incorrect with the triggering (V1.21). It runs correctly on a real c64 (old "breadbox"-version with MOS 6581 SID, but i don't know the version-number of the 6502). |

uh, fixing any c64 stuff to work in a certain emu is just WRONG =P if the emu is broken, the emu should be fixed :)
and i dont think csdb needs emu related flags.... this is a c64 site afterall, not an emulation site.... if it doesnt work in emu, just run it on your c64 :=) |

The Megademo
loader crashs after first pic samples part

both cpu jam's.
I just wanted to see the reaction, about the comment regarding the emulator thing (it was a joke). Maybe I'm totally wrong but a lot of the bugs happen due to loaders/depack routines. If they fixed them 100% then it would clear up a lot of obvious compatability problems? |

unfortunatly it's not that easy. most remaining vice bugs seem to be somehow related to timing inuaccuracies and other weird conditions.
however, it seems vice developers are actually going through the list at the moment, and some stuff appearently is also fixed by now. we'll see what changes in next release (btw the 1.22 version introduced some bugs caused by krills border patches, so you might also want to test with 1.21) |

At least That's Design/Crazy works for me in the latest Vice. It's a matter of disabling the Virtual Device Traps, I think. |

Confirmed, saw that demo many times and works perfectly.
Even HIC megademo works.
TDE ON and VDT OFF must be the default, always. |

thanks for that Steppe / iAN CooG.. ok.. how about a flag in csdb entries that says to turn off drive trapping etc?

VICE could switch virtual device traps off automatically when TDE is active, I guess both traps & TDE on combo is quite useless. The other route is education, but not necessarily here... Actually the age-old C64S did a much better job on educating people, for there was the popup when diskdrive programming was attempted in fast mode. |

That's not true. Try to load a t64 file with traps disabled. Isn't possible. The emulator cannot know if you want to load a "trapped" or a "real" image next. TDE and VDT enabled is best solution in most cases. |

t64 are a failed and bad design. they dont even represent any actual existing media (like d64).
the only good solution imho would be that a t64 gets silently converted into a tap file when you open it, making those damned device traps completely unnecessary. (that should even be quite easy to implement) |

But how many t64 files exist in the gamebase64? Thousands I guess. And it would be a hard job to explain users why we slow down loading of these files by converting them to taps internally.
Some addition to my comments about your current bugfile I sent you on wednesday: I have tested Beyond Dark Castle and Skull & Crossbones/Faces now on my real C64. Both behave exactly the same way as on VICE. They crash/hang. |

i dont't care about gamebase and it's users at all to be honest. accurate emulation is what comes first.
and i really dont think that this conversion will take more than a couple of microseconds either :)

T64 files have absolutely nothing to do with tapes, so there is no reason to convert them to TAP. Better convert them to D64. |

The red storm image from the first link crashes all emulators, I haven't tested real C64 but I will.
The red storm image from c64.ch runs fine on VICE. So probably the image from the first link is broken. |

And just for the records: The removed images crashes on my real thing. And the flickering raster is also visible (even at the lower one if your TV displays enough of the left border).
TRC/TBI intro bug is confirmed. Probably related to a "IRQ cannot be aknowledged just before it starts" bug in VICE that is known for a long time but hard to fix. |

Well, the thread is called "C64 emulator bugs" and if you post "TheWisdom" without any comment (with the comment that the buglist file has to be updated which could mean that "The Wisdom" should be included in this context), I got the impression that TheWisdom IS already tested.
Okay, now that I'm writing this I remember that you're a Linux user and don't have other emulators to crosscheck the file. So please forgive my impatience.

I guess it's a bug in the intro. The check for the raster line takes too long in some frames and so the bad line will delay the D021 change.

Enable #define DEBUG in debug.h and compile VICE, then you'll get several debugging options (for WinVICE look into the File menu, debugging output will be written to the vice.log file).
DEBUG isn't defined for official releases cause it makes thing a little bit slower (even if you don't debug).
And while we're at debugging: Krill implemented some stepping through frames in WinVICE-1.22 (which is available even without DEBUG): Pause emulation with ALT-Pause, then you can step to next frame with ALT-+
Hope that helps. |

Quote: @rubi: ahh yeah ok, nice to know. How is a DMA VICII presented when it's executed in the middle of an RMW-opcode?
See this example (rasterline 59 pixel 5 in my testprog with maincpu clock 8868578 on the first instruction):
.08C1 059 005 8868578 EE 21 D0 INC $D021 A=$08 X=$11 Y=$01 SP=$E6
*** DMA VICII 8868584 43
.08C4 059 054 8868627 EE 21 D0 INC $D021 A=$08 X=$11 Y=$01 SP=$E6
The first inc instructions is executed completely, then the DMA stops the CPU for three cycles (next opcode inc starts with reading bus access) plus 40 DMA cycles so the DMA takes 43 cycles from the CPU.
Now see another example (rasterline 67):
.08C4 067 001 8869078 EE 21 D0 INC $D021 A=$08 X=$1C Y=$01 SP=$E6
.08C7 067 007 8869084 EE 21 D0 INC $D021 A=$08 X=$1C Y=$01 SP=$E6
*** DMA VICII 8869088 41
.08CA 067 054 8869131 EE 21 D0 INC $D021 A=$08 X=$1C Y=$01 SP=$E6
.08CD 067 060 8869137 EE 21 D0 INC $D021 A=$08 X=$1C Y=$01 SP=$E6
Here the INC writes to the bus when the DMA starts pulling BA on low, so the DMA stops the CPU after this instruction and the DMA takes 41 cycles from the CPU.
As you can see there's no easy way to see if an instruction is completely executed before the DMA or not.
Reading the debug will be even harder with sprite DMA (there's no clock output for sprite DMA right now) with some sprites disabled leaving cycles for the CPU but not enough for a complete instruction. See this example:
.08CD 105 051 79868994 EE 21 D0 INC $D021 A=$08 X=$50 Y=$01 SP=$E6
SDMA 1
SDMA 3
SDMA 5
SDMA 7
*** DMA VICII 79868999 16
.08D0 106 010 79869016 EE 21 D0 INC $D021 A=$08 X=$50 Y=$01 SP=$E6

I've noticed a small but quite disturbing bug that comes with the Vice 1.22 and the Viceplus emulator.
When adjusting the volume (to for instance a low-setting) and entering full-screen mode and then re-entering the windows-mode, the volume-setting is set back to full.
I have not tested whether or not this depends on the main volume setting on windows, nevertheless it is disturbing.
Other than that, an ok feature which every emulator should have incorporated!

x64 -truedrive -autostart foo.prg launches with true drive emu disabled. It's disabled to load the prg "fast", but it doesn't re-enable like it does if you autostart a d64.

Well, VICE handles a prg file as a single file on a disk that is represented by the directory of your host system (see "peripheral settings").
LOAD"$",8
LIST
shows the content of the host directory you are attached to. There is no "true drive emulation" for a disk represented by a directory. And how shall VICE know that you need TDE after you have loaded a prg from the directory. Is is more likely that you want to access another prg in the same directory, so VICE stays on the directory. So I really wouldn't call this a bug. |

Not a real emulation issue but it's out of my system now :)
I think it would be easier to link that option in the "open file" window as a check box. so you don't have to start a program twice, cause of switching off itself... just an idea i got... |

i would, if i tell vice to use truedrive emu on commandline, i expect it to use it. end of story. the current behaviour might be acceptable when you DONT explicitly state that truedrive emu should be used, but if you do it isnt.
the same is true for d64 files. whatever nonsense makes vice toggle truedrive emu off/on - it should be possible to disable this.
oh and last not least. when i attach a d81, i want to use 1581 emulation, not 1541 =D |

Actually, I think there should be 3 kinds of behaviour when loading a prg.
1) -> turn true drive emu off
-> use the directory on the pc as 'drive'
-> load the file from the 'drive'
-> basically the same as it is now, problem with cartridges (AR6)
2) -> put the .prg into a temporary .d64
-> keep true drive emulation ON
-> load the file from the temporaty .d64
3) -> simply dump the .prg into the memory (no loading!, actually much like CCS64 does it)
-> keep true drive emu on, but there's no disk in the drive.
Actually I would much prefer the 2nd method, since it is just way more close to a real c64 and stops you from having problems with cartridges/etc, which go b0rk with non-true-drive-emulation.

files should be dumped into mem, and true drive emu never turned off once the user requested it. the current behaviour is very frustrating. |

the most frustrating thing imho is that even when you attach a d64, vice will toggle TDE off/on (so it can cheat on loading the first program). so when i run vice with "x64 bla.d64" and then hit "reset" in ar menu, i end up with TDE switched off (although its enabled in the vice config). that sucks hard. |

because then ONLY d64s will work as expected. i did this a while ago and then it took me a week to figure out WHY THE HELL autostarting t64 and prg doesnt work anymore. (infact, they would not work anymore at all)
like i said before, leave the autostart setting alone. for fast initial loading, toggle warpmode on/off, that would probably be almost as fast, and has zero compatibility problems.
whatever - what really kills me is that such whacked up behaviour ends up beeing the default, and even more, it can even not be switched off at all!. whoever had the bright idea to do it like this should be slapped left and right and in the middle with an extra punch =P |

bugging in VICE
"1541 CPU: Jam in $1200" is normally caused by a BRK encountered during drive
code execution. The loader at $4c00 does a "M-E" $07c0, but there's NO code here.
Just try OPEN1,8,15,"M-E"+CHR$(192)+CHR$(7) and you'll get the same Vice error.
At $0700-$07ff in drive RAM there should be the current BAM (trk18 sect00) and
the loader assumes that on the slack space after the disk name there is some code,
but this d64 is cleaned from extra bytes.

The original code most probably just loaded the rest from the free sectors
in trk18, which are clean too. Recovering this disk is impossible unless the
exact same loader was used and known in another crack.
There are many not working cracks for the same reason, sectors on track 18
carelessly cleaned or even not copied during the dump process. Whole disk
copy on these disks is needed.

I've noticed a bug _not_ visible in (at least) vice 1.13,1.14,1.20 and 1.22. It does show up on the real thing and in (at least) the latest version of Hoxs64.
However, I don't want to share this bit of code yet :P I'll make a safe copy of it, so i can send it to the VICE-team after next year's X-party..

btw, can someone convince The Vice Team to change the default settings to "true drive emulation on" ? It would save a lot of people from frustration who dont know c64 or vice, but would like to watch a few demos/play multiload games. Also its time for a "save settings as.." and fixing the annoying behaviour which causes "true drive emulation" to be turned off.
thank you.
ps, and how about a warm reset option when the cpu jams
ps2, no I wont code it for myself.

Yup, agree totally with what Oswald said..
Ive been wondering forever about some standard features, but especially that true drive emulation thingy. When would an average user NOT want true drive emulation?
Also the monitor jam; sometimes it hangs so badly that any reset/freeze doesnt work and shut-down + reboot is the only solution.. but I guess thats my poor coding doing that.. hehe ;)

it speeds up loading stuff (and won't fuck up the things only if onefiled stuff is loaded of course....)

this is vice problem ;-)
loading binaries in monitor is also fucked up (and is not fixed in vice plus so far) - there is no ability to load binary to other addy (vice takes all the shit as it was PRG so two bytes from start are left even if you actually load RAW binary, not PRG, and there is no controlr over his behaviour at all)
however those bitches ( ;-) )from official VICE team are not interested in fixing some bugs...

What are you talking about? True drive emulation IS enabled by default. You probably mean disabling virtual device traps but that was dicussed here in several postings.
And a warm reset is there since ages (we call it soft reset).
And by the way: Asking for beta tester I got one (1, ONE) answer of someone willing to get a developer release to test for regression (will send it next week). Where are all the guys complaining about bugs in VICE.

like i said in the other thread, you should post links to a binary and a source. making this an ultra secret exclusive thing for a handful selected people wont get you very far. i can very well understand that people dont want to send out a mail and wait for "approval" just to get work done for you, it should be the other way around really. set up a public cvs, and a bugtracker - and you'll get a lot of help, i am sure. |

I think he means warm/soft reset without clearing memory after a cpu jam.
Currently the only way is to enter monitor and do g fce2 manually, probably a choice to soft reset without clearing is to be considered.
Concerning the beta and how vice updates are kept "secret" I have to agree I would prefer to see the modifications as soon they are made, like browsing a cvs/svn repository, and why not, nightly builds. |

Kotze Inside
doesn't run at all in Hoxs 1.0.5.19 if launched from commandline with -quickload, hangs with a grey border.
(seems like the dreaded tde-auto-switch-off hits hoxs too :)
Ccs64 2.0 and Vice 1.20 shows the inital logo correctly.
Vice 1.22/Vice 1.22.8beta, if FULL borders are used, show a grey area on the left (fli bug)

the quick load in Hoxs64 is abit like TDE-off in VICE and is known to be generally less compatible(for example emufuxxored files may fail). i prefer to use the normal load for maximum accuracy+max speed to save waiting.

ive known this bug for a while albeit found it in a different production. i didnt notice it was related to the full/debug borders,i assumed they had fixed the borders-VIC emulation dependence in 1.22.8:) |

I can confirm the "Kotze inside" full border bug (well, I HAVE fixed some border related stuff in 1.22.8 but not enough as it seems).
And I can also confirm the "Bionic Commando Music" bug. I cannot even get a 50% (but a 0%) success rate with 1.22.8.
Now that Andreas Boose has retired from VICE maintenance, we are setting up a public SVN repository. Stay tuned for bug fixes...

@ Groepaz:
Well, as described in my Remarks, the whole thing hangs on 1541U right at the intro, unlike in VICE where it hangs during the first Turn Disk.
I tried it like five times from 1541U, and ONCE the intro worked, but then the whole thing hang at the first Turn Disk, just like in VICE.
Anyhow, I will report the 1541U issue elsewhere, but for here let's stick to Emulators (Software Emulators on so called modern platforms that is) and for the VICE issue a note can be made of. |

@ assiduous:
Thanks for actually checking it and confirming the VICE bug!
As for CCS64: I hardly used CCS64 in recent years but more when it was around V2.0 (long time ago). I don't think the Next Disk/Previous Disk feature was available back then, so I just tried to "turn disk" by pressing F9, selecting the backside and returning to the program, which did not work. Reading your reply, I just tried it again, this time with Next Disk/Previous Disk which worked fine. Thanks for the (indirect) hint ;-)
As for Hoxs: I am afraid I lost concentration today noon after trying this release like 3-5 times on 1541U, then on VICE/CCS64/Hoxs 64. While I believed the release worked fine on Hoxs 64, it failed at my test today noon as described. But obviously I made the following mistake when testing with Hoxs 64: at the second Turn Disk, I re-inserted Side B by mistake, instead of Side A.
I just tested again in Hoxs 64 twice, taking better care while virtually turning disk, and the whole digi demo ran just fine twice. Just to be sure, I tried a third time in Hoxs 64, this time I (re)inserted Side B intentionally at the second Turn Disk where I should have inserted Side A. And see: the demo behaved just like I described (samples playing too fast/too slow/jumping). So it was actually my personal mistake and not a Hoxs 64 issue. Big sorry for that!
I edited my release goof remarks accordingly. |

.C:0814 B9 3C 08 LDA $083C,Y
.C:0817 99 F8 00 STA $00F8,Y
A quick workaround to make it work in any emu and real C64 without patching
the prg is to load it and, before running, issue this poke:
POKE 52991,0:RUN
Or simply fill the memory with 0, but the only important location is $CEFF.
This way at the end of relocation A would be 0, $01 will be set to all ram
and the depack will occour without problems.
CCS64 have reversed fill patterns, and it has $00 at $CEFF, that's why this
crack works there. A real C64, Vice and Hoxs have $ff there, unless you fill
the memory in a different way, of course.

I don't know if this is the right place to post, but here we go...
I was wondering when we can get some ACTUAL fullscreen support in vice under linux... since as it is now, it just 'zooms in'.. meaning that if I move my cursor around I can just navigate across my desktop...
if MPlayer and VLC can go fullscreen, why can't Vice? I know that vice's fullscreen mode changes res, but it would be nice if there was an option to just scale the image or something (with or without keeping aspect ratio).
oh, and for christs sake.. please add a "force true drive emulation" option... I don't see the whole point in NOT having it on anyways...

you have a better chance of having your feature request considered if you post it on sourceforge,this thread is for C64 Emulator Bugs ie.progs that dont work or work incorrectly in the emus. |

there is a sdl port in the works (which will have a user interface vaguely similar to ccs) - that one will easily do "real" fullscreen :)
and the truedrive thing... it will be in 2.1 *afaik* :) |

Found a bug in the DTV emulator of WinVice 2.1.
I checked, and this bug was also in the VicePlus 1.10 version.
It's about the implementation of the $D03C DTV-VIC address.
If $D011 is set to #$1B and bits 5 (cpu bad line disable) and/or 6 (chunky enable) of $D03C are set, Vice should give garbage on the screen but instead it gives a normal picture.
Just found that out while testing Of je worst lust

ahh, now I see why: I had the TFR 0.8 cart inserted.
Happens only with it actually, it's even enough issuing a KILL before launching the intro. I should always remember to try without that cart. |

* 1351 mouse emulation seems to ignore port selection and the upper two bits of $dc00.
* char rom visible to VIC only affects even VIC-banks. If char roms are enabled, these should be seen in all VIC-banks at offset 0x1000, unlike the C64. |

I have discovered some strange bugs in VICE22 which were not in the last one too.. a few not mentioned here..
1. Quick save-states (using alt+s)
1.1: I've noticed after reloading my save states which I was using made the program crash and exit after reloading it a couple of times..
1.2: If you are using the SFX Sound Expander (YM3812) and you reload a 'quick save state' then no sound comes out of the SFX cart.
I know of a few other bugs which I can't recall but will try to re-create and post here and email the VICE team.
I will try and become a beta tester for sure as I use this great program all the time =))
Apart from a few minor issues, this program is still the BEST emulator around by light years..
