I changed your filepath so it matches mine. Am I missing something?
It works!
How can I test the LZ77Decompress you posted, Maki. Or should I wait for your C Version?
Sorry, I'm a noob when it comes down to such things. ^^
I tried it and you guess: Epic fail (or almost)...
At least I could decompress the dat's, that worked. The files in the folder can't be decompressed though. It says "Not LZ77 compressed file; Header is wrong!"
