cvsatdec
Decompresses the graphic data of the playable characters in Symphony of the Night for the Sega Saturn.
Works with ALUCARD.CHR, RICHTER.CHR, RICHTER2.CHR and MARIA.CHR. Their respective PRG files are required as well.
You can use it via command line or just drag and drop the CHR file onto the executable.
Decompressed files will be stored in a <filename>_decompressed folder next to the CHR file.
Note: it doesn't generate image files. You need something like TiledGGD to visualize the decompressed data.
