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 :)

Metalvotze - Kotze Inside
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:) |

Tilt Preview not working in VICE.
Intro works however in HOXS but crashing afterwards
This one would need to be tested on a real c64 to see
if it's working.

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...

Check my remarks for Megamix #01 (loaded samples).
Confirmations from users welcome, as well as comments from Emulator developpers. |

since there are problems with the 1541u too.... it pretty much indicates that the loader/floppy stuff is what doesnt work :) (and yeah, its really broken in vice =P) |

ive checked Megamix #01.

i was unable to reproduce the bug in CCS64 and Hoxs64. i listened to the samples from the start to the end (twice with Hoxs64)with no problem atall. can you please check again ? |

@ 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. |
