I have confirmed that the power turns on. There is a mark on the back where a name sticker was attached to the battery compartment cover and then removed. There are small scratches on the screen, visible depending on the light. The photo on the 9th page is a screen showing the game working, taken over six months ago when I sold a game software on Mercari. You can confirm this by looking back at my sales history (the listing page for the game "Game Boy Gallery 3"). Currently, I do not have any game software, so I have not been able to confirm any functions other than the power turning on. Batteries, software, and other items besides the main unit are not included.
