I need help how to reverse-engineer EXE files - assembly

Postby UndeadHalfOrc » Mar 22 2009, 18:47

WoG experts,

I need help how to reverse-engineer EXE files - assembly debugging, de-compiler, that kind of tool - what can you expert recommend me?

The reason is that I'm desperate to find the offset in the Heroes 2 exe file where is buried the value 10, (0x0A) which is the multiplier for the damage of spells, FireBall, FireBlast, and Cold Ring. I want to change it to 13 like I did with Heroes 3.

So, what tools do you recommend?

Thanks.

Can't you just do that with a hex-editor?

Actually, yes, but finding the offset is the whole problem. Going through the game while using a debugger with well placed breakpoints would help me find it much more easily.

I know this post is a bit old but if you are still looking, I'd recommend becoming familiar with IDA Pro (http://www.hex-rays.com/idapro/) and the Windows Debugger and/or GDB to set breakpoints. I haven't reverse engineered any parts of Heroes 3 but I have done reverse engineering with malicious executables so I may be able to help with this project if you needed. Someone intimately familiar with editing the game may be able to help you more quickly though.
