How to reassemble an executable .exe file?

Question

reverse engineering

Good day, there is an irresistible desire to cheat in the code of one game, but the trouble is that not only is there no source code, but also that it is all one exe file, so the code of interest, which was in principle library (RenderWare3.1) soldered very well. But I would like to be able to make some changes and be able to put it all together. Are there ready-made tools that could do this? (ollydbg seems to be good at disassembling, but there is no convenient way to export to ASM) If not, then I will not refuse advice, perhaps write a plugin for ollydbg, or something else, besides abandoning this matter.

Answer 1

I'm afraid to disappoint you, but reassembly as such for any large binaries is not used in practice. since this would require disassembling the entire file completely correctly, which would be too time consuming.
if you have a small change, it will be easier to find the right place with a debugger / disassembler and patch directly in the binary.
