Aluigi from zenhax told me to post here, so apologizes if this is in the wrong section. I have a .dat file from an arcade game that has some form of custom lzss compression on it, and I'm not sure what it is. Trying anything standard results in a semi correct file. The thread below at zenhax has a bit more info, and I attached 2 compressed & 2 uncompressed files. I'm kinda desperate here, so any help would be greatly appreciated. I also have a .dll that I believe handles decompression, but it also handles a bunch of other game logic (and I'd rather refrain from posting it publicly heh)
Just tested it and it works, you are amazing. Do you have a BTC address I could throw a few bucks at? I've been trying at this for weeks and got absolutely nowhere.
As a bonus, this is how I parsed it (click to zoom). Unfortunately that dll didn't help - there is some lz77 inside, but I didn't find this.
However, ida won't work with structuring of more complicated formats (bitcode etc) :(
