Tropical Freeze Textures: the TXTR format. RTB and Parax pretty much figured it out.

HOOOOLY CRAP!

Random Talking Bush, you are awesome and I owe you an Internet.

EDIT: Your script, for me, seems to spit out jumbled garbage data. I wonder if I'm just extracting the wrong TXTR.

Are you trying to convert the entire folder with a wildcard? It didn't work for me when I did that; I think because it ends up trying to convert the non-TXTR files. Try selecting the TXTRs you want to convert manually.
