Disassembled Games

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.

• 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 link.
• 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. :-)
