It depends on the game the files come from. If, as SmartOne indicated, it's Super Paper Mario, then you need to rename them to *.brstmspm. If it's something else (a different game), then you should probably tell us the game first. When reporting problems, it's best to be as specific as possible (file names can sometimes help, but the game the "bad" file comes from is more useful). Hope that helps. Mouser X over and out.
