DISCUSSIONS on “Rules for online games in HoMM3 and formulas for calculating player rating.”

Dear Wicc, could you please provide more detailed instructions: how, what, and why? We don't disassemble executable files every day, so I'd rather not mess around blindly.

Here are the object codes of the candidates to be disabled:
AVXMAPS0.DEF
...

Do I just need to delete these lines, or is there more to it? In general, if it's not too much trouble, please write everything from "A" to "Z". That is, where can I download a program to open the executable file, etc. And most importantly: will the game glitch afterward if my clumsy hands delete something wrong? Or should simpletons like me just stay away from it to avoid causing trouble?
