Add support for the Game Boy Player

[upintheairsheep]

Hello, can support for the Game Boy Player be added? Not much documentation on the hardware is online, but similar to the GB Link Cable, the Game ROM, Game Save, and BIOS could be added as block drivers. Any DS Slot-2 cartridges with extra RAM or with an SD card slot supported in DSLinux could be ported over, as the GameCube has a limited amount of RAM compared to the Wii.
