Question about recompiling

[abdulahmad]

So is this code in a state to be recompiled once it has been decompiled? I'm not really an assembler programmer so I can't immediately tell.

Was surprised to see the output ad the line numbers/binary code as well-- is there a way to disable that? I assume you can't recompile the code with that in the code.

Also, I've noticed comments about "bad code" or "misplaced" code-- I assume this is something your script does? Would that affect trying to recompile the code?

Yes, that would greatly affect the ability to recompile the code. All of those need to be eliminated first. See step 8 of the README.

Since the main purpose when creating this tool was readability, I decided to keep this information as it is quite handy when investigating code. There's currently no option to turn that off, but a simple regex can be used to remove that, e.g. sed -i -E 's|^[0-9a-f ]+: [0-9a-f ]+ | |g' <file>

No, it isn't. Recompilation is actually way harder than it sounds, as lots of necessary information (e.g. alignment) is lost when compiling sources to an executable (and thus that information is not available when reverse engineering, which is what wcdatool does).

I've had moderate success in recompiling MK1.EXE, but its structure is way simpler than MKTRIL.EXE. Plus, prior to refining wcdatool's output (again, step 8 of the README) it's not even worth trying.

You might also want to browse through #9 and #11, which contain answers to lots of questions regarding what the output means, what can be done with it and so on.
