Atari 2600 Programming Page
This page contains actual Atari games, disassembled and reverse
engineered. That is, they're 6502 listings with comments
that tell you what is going on in the code.
Defender Updated 2/24/97. Far from even
close to coherent, but it does compile.
- Combat Updated 2/26/97. Reverse-engineered
by Nick Bensema. One of the first public-released reverse-engineering
attempts. Compiles with DASM.
- Solaris --
original source code by Doug Neubauer, transcribed by Bob Colbert. Off-site
- Adventure, disassembled by Simon Cornwell.
Almost every line of code
is explained here. Strange format, hex numbers have & and there are
no equates; it is allegedly based on BBC Micro assembler language. But
still a smashing job.
VGR used these notes to write a DOS clone
of the game, called Indenture. Find out more about the game from the author
himself, including a PowerPoint presentation, at Warren Robinett's Adventure page.
- Freeway Reverse-engineered by Bill Heineman,
Very complete. Compiles on an Apple II; it's that old. :-)
