Okay, so weird fact about this game; despite the label claiming the game is "only for the Gameboy Color", it of course also works on the original Gameboy, as it is a black cart rather than see-through... But more curious, there's a very uncommon grey cartridge floating around, because the game also got a release for the original Gameboy, but it's very hard to find info on it. We have a feeling that version will be rare in the future, when the internet realizes it exists, so look out for it! Condition : Great.
