I'm a novice, but I've checked the operation and believe there are no issues. Please understand that this is not a perfect operational check. Also, the battery is bad, but the power turned on while charging. Both units are missing batteries and battery covers. The black PSP makes the "kyuru-kyuru" sound when starting a game. The only included items are the main units. These are used items, so please understand that they are sold as-is, with no returns. Please ask any questions in the comments! ※Important※ Shipping time is set with some leeway! If I can ship it sooner, I will try to send it out on the same day. This item will be shipped via Nekopos (a Japanese delivery service)!
