How to make sense of disassembly?

Jonathan Drain · 27 October 2009, 22:29

I've been disassembling Amiga games to look for secrets and cheat codes, and maybe to rip game data and examine game mechanics. By applying IRA V2.02 and digging through asm I found the cheat codes in K240, though unfortunately only the twelve codes that are already known.

How make sense of a program without the original source, and read its data files?

One approach (and the only one I've ever used) is to look at the hardware interrupts and to characterize the chain of calling functions accordingly in a bottom up fashion.
