Thank you for viewing. Price negotiations are possible, but only to a small extent. This is a Nintendo Super Famicom console. It comes with a Super Game Boy, so you can also play Game Boy games. Operation has been confirmed. I tested it with seven game cartridges I had at home (Pokemon, Puyo Puyo, etc.), and they all worked fine. However, there is a possibility that it may not start up properly depending on the compatibility with the device or the environment. We cannot guarantee certain operation, so please understand that this is a used item before purchasing. As it is an old item, there are some discoloration, scratches, and stains. [Confirmation Items] The game cartridges used for operation confirmation are not included. To prevent replacement, we do not accept returns, exchanges, or refunds. Thank you for your understanding.
