[Peppers]

yes you can build dev charts but you will require a different one for every memory mapper and a differint one for RAM supported ppu games and ROM supported PPU games for each of these mappers. If you were to build a dev cart for every memory mapper the powerpac's FPGA emulates it would be much more costly and switching programs would be more difficult because you would have to program whatever type of eporm/eeprom you choose.

although doing that has the benefit of no question of the mapper accuratacy
