UniMapper MSX (MSX universal mapper cartridge) 5 min read

The MSX Unimapper is a cartridge platform for MSX computers that separately supports 4 different mappers and allows to launch software and game ROMs up to 512kb on any compatible MSX system. The mappers are emulated by 2 or 3 programmable logic (PLD) GAL22V10 chips. Each mapper requires its own firmware to be programmed into the PLDs. The cartridge platform includes 2 different variants of the same cartridge.
