Game Boy Donkey Kong GB cartridge. The game functioned without issue during gameplay. (If it doesn't work correctly, please try re-inserting the cartridge several times.) This is the cartridge only; the Game Boy console itself is not included. ・Game data may be present. Please understand that this is a used item before purchasing. ⚫︎It will be shipped via Yu-Packet Post Mini. I'm also listing several other cartridges, so feel free to request a combined purchase, etc.
