How do I trade between blue and crystal? The ports on the original gameboy and the gameboy color are different. Also, are there any exploits when trading back to gen 1?
If both players are using a Game Boy Advance, Game Boy Advance SP, Game Boy Color, or Game Boy Pocket, you can use a Game Boy Color Link Cable (model number CGB-003), or a Game Boy Pocket Link Cable (model number MGB-008), or a Universal Game Link Cable (model number MGB-010) to connect them. If the cable does not fit, it is the wrong type.
You either need to use a link cable that can connect to one type of GameBoy on one side and a different type on another or use the same type of GameBoy. If I'm not mistaken, the Gen 1 games can be played on the GameBoy Color, and Gen 2 games can be played on the original GameBoy, and both can be played on the GBA.
