SEGA GAME GEAR 8M-BIT MASK ROM (Garfield)
The Pinout diagram shown below applies to MASK ROMs that interface with the SEGA 315-5912 Paging chip. MASK ROMs for GG games such as "Virtua Fighter Animation", "Sonic Blast" and "Garfield" as shown here, all use the 315-5912 mapper. The pin layout shown below is the same as the MX IC "MX23C8000" 8M-BIT CMOS MASK ROM.
