Wot dur hell. I didn't know I could do this! Just found out about it a couple days ago, and so I was curious. You should only do this if you own the physical GBA cartridge (idontown3ofthem)*cough*. Oh frig off, I gave Nintendo a lot of my monies already. I gotta say, it's very convenient. It's much better than the PSP, you know, since the PSP battery sucks and is always draining out/too fast.
