I'm trying to reverse engineering zlib, it seems to be obfuscated in some way.

i'd think it would be easier to look at the files in the game folder. but i have no experience so this post is completely meaningless lol

I know how but I'm not going to tell you.

The files are often contained and compressed into some type of zip folders. You have to look at the hexdump and see what type of compression it has, then unpack it.

it's possible but will be different from case to case. You could hook the audio library calls and set a breakpoint there, go up the stack to find out where it was called from, that's a start. Also good tip is to look for strings in the binary, especially for errors. Shit like "can't init audio" or stuff like that. At least you'll know you are in some audio setup function then.

Research?

I don't think different games use similar formats in their data files.

Reverse engineering work is mind bendingly hard because you basically have to infer from the result the various components that make the said result. It is similar to guessing the actual exact colors that mixed to produce another color. Hard but not impossible.

Ghidra's actually pretty nice, just make sure to changes access for the backdoor server it adds.
