Game Boy/Game Boy Color

To run homebrew or ROMs on your Gameboy/Gameboy Color you'll need a flashcart.

There are two Gameboy/Gameboy color flashcarts currently available.

The USB 64M Smart Card is a usb based flash cart that can support up to 64Mb of roms (So, about 8MB), however, there is only one save slot available, regardless of how many games you have on it.

The other option is the Everdrive GB, which has an SD slot and can support any number of games and saves, however it is twice the price of the previous flashcart.
