The Retro Lite CM4 is a passion project by two modders StonedEdge and Dmcke5, inspired by the Switch. This emulation handheld is based around the Raspberry Pi CM4 and RetroPie.

While sharing a very similar look to the Switch, this thing is been built from the ground up, with a custom machined shell, PCB, and various other components. There's an optional custom dock with an integrated LCD, that can show the current game's cover art.

Personally, I think this is absolutely impressive. Hats off to these guys!
