INES Mapper 111
iNES Mapper 111 denotes the unrelated GTROM circuit board and an MMC1 variant used in a Chinese homebrew translation of Ninja Ryuukenden.
See: GTROM
Prior to the introduction of GTROM, Mapper 111 was assigned to a Chinese homebrew translation of Ninja Ryukenden (Japanese version of Ninja Gaiden). This translation uses a non-serialized version of MMC1 and supports 256KiB of CHR-ROM, whereas the official MMC1 is limited to 128KiB. This assignment can coexist with GTROM provided the emulator recognizes that the translation uses CHR-ROM and therefore must emulate the MMC1 variant instead of GTROM hardware.
A possibly later version of the translation uses MMC3 instead of this MMC1 variant.
