Utility description

A tool for compressing and decompressing data in GameBoy Advance games:

1606 - B-Densetsu! Battle B-Daman - Moero! B-Tamashii! (J),
2414 - B-Densetsu! Battle B-Daman - Fire Spirit! Honootamashii! (J),
2463 - Battle B-Daman (U),
2507 - Battle B-Daman - Fire Spirits (U).

and possibly other Atlus games. Compression is used mostly for graphics data, such as tiles and tilemaps. For tiles this tool shows 3-5% better compression than original packer, and same or slightly better compression for other data.
