So, if you don't understand this, back in about 2004, Nintendo released a series of GBA cartridges that contained TV shows and movies, like Spongebob and Shrek, instead of games. It was called GBA Video. To prevent Piracy, Nintendo made GBA Video incompatible with the Game Boy Player accessory for the Gamecube. The Video could've been fed through a VCR, which could then be recorded to tape.
