Cheat Engine

[sully71486]

I'd like to be able to play a 32bit x86 game (20 years old), hopefully at, say, at least 10% of normal speed, and have the debugger log to a file each time a new code branch is taken. So initially it would have tons of output and over time that'd slow, but I guess the debugger would be checking upon each call/jump whether the destination had already been logged.

Is CheatEngine an appropriate tool for this? If so, does it need a modern Intel processor like for ultimap2? If not, would ollydbg be more appropriate?

ultimap1 also does that (bit still needs an intel cpu)

alternatively the code filter ( https://youtu.be/csrU18C4rWY ) could be used, but for 32-bit you will need to do some work building a proper list of addresses
Build a list of all calls but that will include some invalid results
I recommend using the debugger option to break on unexpected breakpoints and on errors check if there is a wrong 'cc' there and if so, remove that from the list and try again (keep the new list)
