• MPR (often .mpr or .gdi+bin combo): a packaged game image format used for Dreamcast/arcade ROMs; MPR can be a raw binary image of a GD-ROM or cartridge dump.
• 21931 / IC501: these look like device or component labels—commonly, IC501 could be an identifier inside firmware or a file within a ROM image. “21931” may be a build/part number or checksum tag.
