I purchased a product from Retro Reborn on Mercari. The included accessory is the power cable. It has only been used a few times and is in good condition, with no operational issues. The game used for testing during startup is not included. The product specifications are as follows: * Latest IPS LCD panel V7 (Made by HISPEEDIDO) * 3.0-inch display * 9x pixel count * 178° viewing angle * Equipped with an OSD menu └ Accessed by long-pressing the center button * 15-level brightness adjustment ├ Adjusted with the center button └ Adjusted with the touch sensor on the bottom right of the screen * 8 color modes └ Changed with the touch sensor on the bottom center of the screen * New 900mAh battery replaced
