It look like a joystick, but is actually a plug and play video game systems that have the games built into them. The cool thing is that they are self contained systems. You don’t need game cartridges, complicated cables, or AC adapters. They are powered by 4 AA batteries and have the A/V cable built into the system.
After you install the batteries, you plug the RCA style video and audio cable into a set of free input jacks on your TV. Then you turn on the TV, switch to the input that you just plugged into, flip the On/Off switch on the game system to on and there you go, you can play games.
