Heheh. Yeah, thank you very much.

So how would I go about replacing it?

I'm a noobie so bear with me. Just got my Pi (rpi2) yesterday and immediately set up recalbox. After I installed all my games I noticed that the gba games weren't working. When I go to start them up, the screen fades into black, and then fades back into the UI. This doesn't happen with any of the other emulators I've tried (Genesis, SNES, PSX, N64). I haven't messed with any configs so I don't really know what to do.
