> Are there any guides on tools used for extracting source from binaries? For example, I'd love to be able to read the files on the Ultima V main program disk and convert the binaries to actual source code (either assembly or c) so that I can go through it with a fine-tooth comb and see how things are done, perhaps add some logic of my own or fix some issues and then recompile. I know Burger Becky is a master at this. Thoughts?

You are looking for a 6502 disassembler. 

Why?

* 95% of games were written in assembly.
* A few were written in Applesoft with machine language supplements (Ultima 1, Empire 1: World Builders, etc)
* A handful were written in Pascal.

On the PC side of things the popular disassemblers are:

IDA

Sourcer -- no longer sold

Richard Garriot was learning 6502 back in Ultima 1 so it was a hybrid written in Applesoft and Assembly. By the time Ultima 5 rolled around (March 1988) it was written 100% in assembly.  C didn't popular for games until the 1990's and Marble Madness.

I'm not sure what Apple 2 disassemblers people are using aside from AppleWin.

I'm in the process of adding 65c02 support to dcc6502.

Will be interesting to get a list of popular tools.
