Peace be upon you, an old version Nintendo Switch, not hacked or modified, and it comes with the Mario game cartridge, the version shown on the screen. The cartridge is wiped but works with you without any problems. The device is clean and does not suffer from any problems except for the absence of the stand that holds the device from the back and the cover for the cartridge slot does not close completely (minor issues that do not affect the device's performance). Also, the controllers are missing, but you can buy them and attach them to the device, and they will work with you normally. For your information, you will likely not be able to open the game interface on the device unless you buy controllers for it, as I will format it before handing it over to you. Please do not undervalue the item.
