Continues from **https://reverseengineering.stackexchange.com/questions/6527/unknown-game-data-compression-method-gamecube<br>** I have compression data which was start with: **[ * SK_ASC* ]** and unknown compression method.<br>The list below compression method that I tested, but doesn't match: - LZ10 - LZ11 - LZ77 - LZO1x-1 - LZO1x-999 - LZSS - LZW - LZMA - HUFF blocksize 4 & 8 byte - RLE - ZLIB **Researching for 2 weeks**, I knew that compression algorithms is slightly modified, better than zlib/gzip.<br> It maybe xored or encrypted so it doesn't match with regular one.<br> **Finally**, I've found decompression subroutine from main executive file via **IDA Pro**.<br><br> Subroutine & example uploaded here: **http://goo.gl/2bQNfj** <br>**(PowerPC Architecture Assembly skill required)**<br><br><br> I have no idea what It mean cause I'm not well in PPC disassemble.<br> Could anyone help found out what the code mean? Could you describe it as C Language or other readable language? <br><br><br> **P.S. I already posted several forum to help.** - http:// zenhax.com/viewtopic.php?f=9&t=313&sid=3172c154c5da95476795ac742501fec1 - http:// forum.xentax.com/viewtopic.php?f=21&t=12136&sid=de570647f5b1abe2cff5c3dcf2eccb16 - http:// encode.ru/threads/2074-Identifying-compression-method
