I know this is stupid, but I heard you can play GBA games on your Gamecube. Is it possible?
If so, please tell how.
All you need is a Gameboy adaptor for your Gamecube. I don't think Nintendo really makes them anymore, considering they were released in 2003, so I think you might need to get one 2nd hand.
All that said, here's a link to Amazon selling the item.
