Meet the MintyPico: a programmable arcade in a tin can with a 128 x 64 1.3 inch display, RP2040 chip and 100mAh battery. It has a couple buttons that let you start games and switch mode. The four right buttons can be used to operate the games. As you can see in the below GIF, you can play a bunch of classic games on this.
This tiny gaming console comes pre-loaded with 5 games. The project is currently on Kickstarter. You can find out more about it here.
