Hyperkin's new RetroN 4 console is designed to play NES, SNES, Genesis, and Game Boy Advance cartridges. It's compatible with both PAL and NTSC formats, has dedicated controller ports for NES, SNES, and Genesis controllers (and uses its own Bluetooth controller), and uses HDMI output. A special UI built into the console allows users to reassign buttons, among other things.
More details about the console will be revealed at the Midwest Gaming Classic in Brookfield, Wisconsin on March 23. That includes pictures of the device.
Who ever thought you could get away with announcing a new console, the fourth in its series, with details of its functionality but no pictures of the console itself? Honestly.
