I made couple disassemblings

Postby Petari » 09 Jun 2009, 15:41

For Atari ST. Games: Prince of Persia. Sideways. Complete disassembles, and may reassemble them. Unchanged disasm will work well. Some changes too. Some changes may require additional analysis of code....

Disasm of Sideways is avaialble here: http://ppera.07x.net/forum/ (need to register for DL). I will post src for Prince of Persia if interested.

Adapted games (for hard disk, saving snapshots) for Atari are here: http://ppera.07x.net/atari123/fromhd.php

Hi Petari,

Nice to see you here. I used to read you on Atari forum and AtariAge.

I didn't know you disassembled some games. Prince of Persia source may be interesting, not only for me. Do you have commented some parts of it?

By the way, i always wanted to thank you for all you works, mainly for FloImg which i used to successfully dump my damaged french version of "La Hanse". It probably couldn't have been done without it. Big thanks.

I wish you all the best,
Kroah

Hi ! i'm here after 2 years :D Some adresses changed in meantime - now at http://atari.8bitchip.info .

Considering Prince of Persia. I disassembled it because game was badly coded - I saw many bad solutions. There is not much comment in disasm. I updated only some parts - mostly register usages by TOS calls, what made problems by higher TOS versions.
In any case, game could be improved by keeping graphic and updating some parts of code. In first place sound playback code, what is inefficient and slows down. Of course STE DMA playback would be best. It is actually not hard to solve. Probably most work would be with converting samples to proper format.

Mail me for more - petari@8bitchip.info
