It's called Master TV Game or something like that. I only got the unit, no controllers or power supply. The on/off button is on the side. The triangle on top is a reset button. I used a 9V power supply from a PowerJoy to test. No built in games but I had a PJ-008 cart and it works. Printed on the board inside says: Oct 10 2002 GM-811M1 Gaoming R&D.
