GCN gcfsysd help (FSYS ripping)

[Essa]

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.
