And no, don't make a Game Boy Advance joke, you smartass. Hyperkin's Supaboy is an upcoming handheld unit that's actually a Super Nintendo. Like, you have to insert Super Nintendo cartridges to play it.
Currently slated for a North American release, the Supaboy will play both American and Japanese carts. It also supports multiplayer, as you can either game alone using the in-built LCD screen or plug it into a TV, and use actual SNES pads (not inlcuded) to duke it out.
It runs on a rechargeable battery, giving an estimated 5-5.5 hours of battery life, and should be out this (northern) summer.
There's no word on price yet, but other Hyperkin SNES-compatible consoles go for between $US60-$US70, so this shouldn't be too far off that mark.
