Need help extracting Skylanders .arc files

[MontztheMan]

The closest BMS script I can find for this .arc file format is the Marvel Ultimate Alliance 2 bms (which makes sense, both games have the same engine, presumably). The script extracts .arc files into neatly organized folders but the actual files themselves are in what looks like a corrupted format.

For example the file "airdragon.arc" extracts into the folder "tfb\build\wii\models\characters\minionsmonsters\upgradeposes\airdragon\final\airdragon_upgradepowwow.png" but the file itself is "0x9f88703e.png.igb.tex.igz"

I'm very new to BMS stuff and I don't really know how to modify the bms script to extract the file correctly. The script and the above mentioned .arc file are attached below. Any tips?
