As said in the first comment about this release, it was done from the Six Appeal compilation.

ian coog: ... and there it is, the proper IRQ deactivation code :) Apparently, the Myth version is defrozen/defreezed (thawed?) from some compilation, and not cracked from the original tape, which could explain the missing init code. So TWR is to blame, after all :)

I didn't check the original myself -- thanks for the info.

Actually there is no bug in the game code, if you make it start from $0400 instead of $0810. Had a look at the original tape and the needed init code was there, just before the jmp $0810.

@/j0x: I would suggest you just add your fixed version as a seperated entry in csdb and refer to vice versa version :)

Ian Coog: Nope, it's not a bank switching issue. Looking at the code (as you've obviously done), you can see that every memory configuration works, as long as I/O mem is switched on. The bug is caused by the program switching off timer interrupts (lda #$7f sta $dc0d) without acknowledging any pending timer interrupts (by doing e.g. lda $dc0d). Sometimes, a timer interrupt has been triggered before they're switched off, and hence, as soon as the interrupt flag is cleared, a timer interrupt occurs, which is never acknowledged.

Slator et al.: Nobody's talking about changing the past. I did this because I was curious why it didn't always work under Vice (or on the real thing, for that matter). I fixed it, re-attached the original intro and crunched it using the "tools of old", just for fun. My reason for suggesting a release of the fix was to improve the "Software Library" here, not to make TWR or Myth look better. Interestingly, the bug is in the game code, and thus not directly caused by TWR.

Cheers!

For sure you don't touch the original version to fix it in here. No man should change the crimes of our history :D
But you easily see who cared for quality back then and who did not ;-D

Yep... Better re-release this one.

@iopop: Just the problem that I found myself games in GB64 that crash right at the first level! :)

There was a time when I pestered them with emails describing the bugs and supplying a working version :)

Naturally the games at http://www.c64files.com work better. (most are tested)

Emulators are good for packing or fast checks, use the real thing instead.

Damn PC-cattle...

I agree 100% with iopop, we shouldn't try and change the history.
Add the fixed version as a separate entry instead.

Iopop has a point. My version works 100% on a real c64.
User Comment
Submitted by iopop on 14 October 2005
In my opinion "the fix" should not be added at all. Atleast not as the same entry as the real release and esepcially not in a version that tries to be as similar to the original as possible. Why? Because its history revision.

If someone released a buggy crack some 15 years ago, so be it, many have done it. And if you really want to play the game, there's prolly another version at gamebase64.com that works.

Thanks for your commitment, jOx. I was actually going to re-crack it this weekend, and then pack it with a normal basic sys start instead of using the compounder. Now I don't have to do it. Thanks. Maybe you want to add a "bug-fix" credit...? It would be ok with me for sure.

In case anybody's interested, I just fixed this one to work with Vice.

Unpacked the game, fixed it (IRQ wasn't always properly acknowledged), stuck the Myth intro back on, and finally crunched it using the same cruncher as the original, for that old-skool feeling.

I also played it through to the end to make sure I hadn't introduced any bugs.

I don't know the proper procedure for submitting fixes on CSDB (assuming it's alright with TWR) -- perhaps someone can enlighten me?

Then I guess it don't work on Vice. I don't use Vice.

It hangs after the intro here too, using VICE 1.16.

A great game cracked from a compilation called Six Appeal.
