I recently acquired a red GBC from one of my friends, but it doesn't work at all. I've tried on the Game Boy Pocket, Advance, and Advance SP. I put it in, turn it on, and the start-up screens play as normal, but after that, nothing. The screen goes blank. Any advice?
Quick edit; I've tested the Game Boy Pocket with a game cartridge and it worked fine, so I know it's not a problem with the Game Boy itself.
