The PS One console has been customized to run on USB power. The back has been modified for this purpose. If you have one, you can also use the standard AC adapter. Both have been tested and confirmed to work, but please do not plug them in simultaneously. We are not responsible for any malfunctions or damage that may occur if you do so. This set includes a controller, connection cable, game software, and a memory card. We have confirmed the console and games are working with several games, and will include World Stadium EX for testing purposes. The game software is in great condition with no scratches and the original obi (sleeve). We have confirmed that it functions properly as a CD player. This item is also listed on other flea market sites, so it may become unavailable.
