 --------------------------
 Pirate MMC3 variant

 Dai-2-Ji - Super Robot Taisen (As)
 
 
 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 $00-$01 are CHR-RAM, other pages are CHR-ROM.
 
 Apart from that, this mapper behaves exactly like your typical MMC3.  See mapper 004 for details.

A NES 2.0-compliant image and emulator will treat mappers 194 and 195 the same; they both specify CHR-RAM pages start at 0 and contain no mirrors.

Mappers 252 and 253, also used for Waixing's localizations, are similar but use a VRC4.
