INES Mapper 192

iNES Mapper 192 is used to designate a board, used by Chinese developers, similar in capability to TQROM (iNES Mapper 119). It uses a clone of the MMC3 but uses the CHR bank number in such a way so as to allow both CHR ROM and CHR RAM to be used simultaneously.

Mapper 192 games are thought to follow a similar strategy to Faxanadu, reserving some CHR RAM for software-rendered text boxes. No mapper has enough CHR ROM banks to allow showing dialogue using Chinese characters with only CHR ROM and without prerendering each sentence, and unlike Japanese, Chinese cannot use the common shortcut of using only phonetic characters.

Registers

Registers resemble MMC3, except CHR ROM banks 8, 9, 10, and 11 are CHR RAM. Other (unknown) inaccuracies compared to an authentic MMC3 may be present.
