This section is all about projects
I've done to alter the Memory Mapper Chip a game uses. Typically these
games will use a japanese only Memory Mapper Chip such as Namco 106
which may not be supported by your favorite emulator, PowerPAK
cartridge, or does not exist in US cartridges that you want to use to
build a reproduction cartridge. So the game is then hacked to no longer
use the japanese mapper but instead to use a US alternative. Sometimes
this is difficult depending on the original mappers capabilities and
just on a game by game basis. Anyway, here are the Mapper Ports I've
done.
