Ida + Hex Editor + maybe something else will be useful.

SoftICE is a powerful tool, but you need to understand how it works to use it effectively!

There are mods for NCF and Heroes 5.5.

You can work with unpacked .exe files, but even in those, someone who's an expert will have a hard time figuring out where everything comes from! :smile42:
