iNES Mapper 074 is a MMC3 clone used in Eastern games. It's identical to iNES Mapper 192 and used for the same reason, except that only pages 8 and 9 are RAM. If the NES 2.0 header is present, 74 and 192 should be emulated identically, as NES 2.0 specifies CHR RAM size elsewhere.
Here are Disch's original notes: ======================== = Mapper 074 = ======================== aka: -------------------------- Pirate MMC3 variant Example Games: -------------------------- Di 4 Ci - Ji Qi Ren Dai Zhan Ji Jia Zhan Shi Notes: -------------------------- This mapper is a modified MMC3 (or is based on MMC3?). In addition to any CHR-ROM present, there is also an additional 2k of CHR-RAM which is selectable. CHR pages $08 and $09 select CHR-RAM, other pages select CHR-ROM Apart from that, this mapper behaves exactly like your typical MMC3. See mapper 004 for details.
