GBA SP Emulator

Download > Visual Gameboy Advance and GBA SP ROMS

Because the insides of the GBA SP are the same as the ones of Gameboy Advance you can play all GBA SP games with GB Advance Emulator (link above)

Nintendo Pokemon Emulator systems are not spared from being turned into gray market goods, because there are already GameBoy Advance imitations out there. An example of such is the Deal Extreme GameBoy Advance or GBA clone; there are also imitations of GameBoy Advance SP available in the bootlegs stores. And of course, they are not found in legit shops and resellers - most of them can be purchased only in the Internet. For real gaming geeks, these are a must-have.
