It's all about the tga's. They exist from 6 tga's, each with a specific code at the end of the name to specify if they're the top, bottom, or one of the other tga's. These codes are: up, dn, lf, rt, bk, ft. Just create bitmaps (256x256) and later convert them to .tga's. Keep in mind that a player only needs the .tga files...
