It is not a "paka paka" (slang for a specific type of game). There are stains on the cover and case. Please consider the cover and case as extras; if you don't need them, I will dispose of them. Operation has been confirmed. The case has been wiped with alcohol. I am selling this to organize my collection. I will clean it as much as possible and carefully pack it for shipping. If you have any questions, please feel free to comment. I think it will be easier to find other products, so please search if you'd like. #mifukata's games #mifukata's PSP
