/vr/ - Retro Games

Posted on /v/, but nobody knew/replied. Anyone know how to extract sprites from Build ART files? Every program I've tried (and I've tried a lot) either doesn't work with Ion Maiden's ART file, or produces scrambled images. Is it encrypted? The GRP file is perfectly accessible, and I've been able to pull the music and sound effects without any problems. Mostly I just want Shelly's expressions, because they make for good avatars. But there are too many to rip from screenshots.
