Victor Ongen's Game Boy game "FLAPPY". Tested and working. Complete with box. The box has some wear and tear due to age, and two of the flaps are missing. The cartridge is in typical used condition, but there is a sticker on the back. Will ship promptly via Mercari shipping, etc. #Puzzle #gb #gameboy #Nintendo #Nintendo #HiddenTechnique #200 #Xevius #BlueStar #Unicorn #Ebira #Rare #Rare #Valuable #Retro #Rare
