Hyperkin's RetroN4 is a one-stop shop for anyone looking to dig deep into the history of gaming.
The unofficial retro game cartridge player plays NES, SNES, Nintendo Game Boy, and Sega Genesis games. Looking to try some imports? The device plays NTSC and PAL-formatted games. Also, it hasn't been sitting in your parents' basement.
As for controllers, the console has ports for all each controller type. If you'd prefer something cordless, though, it comes with a wireless bluetooth controller that works for all four systems. There also other modern amenities like, HDMI and a UI overlay that lets players customize the wireless controller's layout.
Hyperkin will announce more details about the device, including the price and actual pictures of the device, at the Midwest Gaming Classic in Brookfield, WI March 23rd. I'm guessing it'll be more expensive than an actual Game Boy, but less than a gaming PC.
