Thank you for viewing. This is a listing for all 4 game cartridges of the Mega Man Zero series for the Game Boy Advance, cartridges only. ● Mega Man Zero 1 (New battery installed) ● Mega Man Zero 2 (New battery installed) ● Mega Man Zero 3 (Flash memory installed) ● Mega Man Zero 4 (Flash memory installed) This is part of a collection clear-out. New batteries have been replaced, terminals cleaned, and operation has been confirmed. Please note that price reductions are not possible. The game cartridges... I think they are in good condition, aside from some scratches on the insertion part. Please check the attached images. Due to their age, if you are sensitive to such things, please refrain from purchasing. In addition, there are no pets involved. After purchase, I will package them with waterproof measures (in a plastic bag) and cushioning material, and ship them anonymously via Yu-Packet Post Mini within 24 hours. #Nintendo #Retro #Valuable #RetroGame #GameBoyAdvance #Other #zero #MegaManZero
