There is a commercial program called Sourcer that is advertised fairly
regularly in PC Magazine that will take binaries and turn them back
into (semi-)commented assembler code (I call it semi-commented because
while the program will tell you what the program is playing with, it
can't know what the intent of the programmer is, so you have to go by
context).
