After 20 years since I last coded anything on 8bit Atari, I decided to try again to play with some 6502 assembly.
The result you will find in attachment - a WIP of Great Escape game ported to Atari 8bit from C64. Game seems to be quite playable, but there are still various issues, so it is considered "alpha" now.
I am going to work on this port to finish it someday, but I need some help.
1. I need sound effects for the game. It looks that there are not many, but roll call is definitely required. Since I am not musician or sfx composer, I need somebody with proper skills to get the job done.
2. Music for the game. The problem is that there is only 4KB of RAM free and there is not much time in frame left for player (actually there is no time, as game is pretty slow, but still faster than on C64) but music may improve the gameplay.
3. Loading picture. C64 picture would be probably easy to convert, but it doesn't look good in my opinion. ZX-Spectrum title screen is much better, but my preferred one is here: http://speccy-live.u...raig-stevenson/. Not sure if it is possible on Atari.
4. Hints on possible optimizations and bugfixes are also welcome!
Game screen will be also improved to follow C64 look. Hopefully PMG coloring on inverse hires will do the job. If you have some better ideas, please let me know.
Attached ge.obx will work only on Altirra, as it loads directly under OS ROM in current form, so it will not work on real Atari. This issue will be addressed later.
Enjoy Great Escape!
