I was browsing through the Pokemon Colosseum ISO/GCM and I found that all the files, (except some .samp) were fsys. I know there are some of those in Pokemon Battle Revolution and to me they seem similar to .SZS files. I'm fimilar with texture hacking mario kart wii. But this program called gcfsysd which uncompresses the fsys is not working, I do not know how to make it work. This Pokemon Battle Revolution on Wii files (*fsys) compression method, using a gcfsysd.exe can extract two LZSS compressed files, but i is unknown compression, try standard decompress tool, doesn't work here is the files http://www.2shared.com/file/10907442/aa ... r_wii.html it contains pkx_001.fsys gcfsysd.exe pkx_001.000 pkx_001.001 use the gcfsysd.exe can extract pkx_001.* pkx_001.* are LZSS compress Link to gcfsysd is found here: http://hcs64.com/vgm_ripping.html If someone could tell me how to use command prompt or whatever to make this work that would be appreciated. (I'm trying to hack Pokemon Colosseum to make new characters, story lines, battles, areas, ECT. NOTE: IM A NOOB I JUST SIGNED UP if this is the wrong topic move it please... Thanks for reading.
