Game Boy Software "Captain Tsubasa VS" This is an authentic product manufactured by TECMO. - Software cartridge included - Clear case included - Outer box and instruction manual NOT included As this has been stored for a long time, the software and case have yellowing, dirt, scuffs, and signs of use. The label also shows deterioration, so please be sure to check the condition in the photos. As I do not have a Game Boy unit, the operation has not been confirmed. Therefore, it is being listed as junk. Recommended for collectors, retro game enthusiasts, or those looking for items to repair or maintain. Please only purchase if you understand that this is a used item with unconfirmed operation. Those seeking perfect condition should refrain from purchasing. It will be shipped with waterproofing measures in place, via anonymous delivery.
