Super Famicom Game Software Super Ninja-kun Thank you for viewing. I rubbed the dirt on the back with a sticker remover, and part of it has become rough. The dirt is not completely gone either (see photo). Operation has been confirmed. Returns and refunds are not possible due to the software not working. Please purchase only if you understand that this is amateur storage. If you would like to see more photos or have any questions, please feel free to ask!
