The FinalGROM 99 supports ROM images, GROM images, and mixed images of
up to 1 MB in size that use the write-to-ROM bank switching scheme. The
cartridge does not require the Peripheral Expansion Box and runs on both
PAL and NTSC consoles, including modified consoles with an F18A. It
will also run on v2.2 consoles and enables those to run ROM-only
programs. It will NOT run on QI motherboards
