The My Arcade Retro Champ is essentially a Nintendo version of the Game Gear that never existed. It’s a portable console you can use to play both old-school Nintendo Entertainment System (NES) and Famicom cartridges.
The Retro Champ features a 7-inch LCD screen for playing on the go, similar to the Nintendo Switch. And just like Nintendo’s latest console, this portable NES features a kickstand that props up the console when you’re tired of holding it.
Alternatively, users can plug in the Retro Champ into a TV using the HDMI port located on the back of the device to play their retro games on the big screen. Of course, you’ll want a controller for this type of play and users can connect this system to one of My Arcade’s wireless controllers like the SuperPad—which didn’t add any discernible lag to me.
