Like [[TQROM]], mapper 74 has CHR ROM on some CHR pages and CHR RAM on others.
It's identical to [[iNES Mapper 192]] and used for the same reason, except that only pages 8 and 9 are RAM.
This is necessary because the large number of characters in the Chinese writing system precludes having them all in one CHR ROM bank, so they're copied into CHR RAM as needed.
But instead of CHR pages 64 through 127 being RAM like in TQROM, only pages 8 and 9 are RAM.
