Essentially, this is a little handheld Neo emulator with all the right controls and twenty games built in. There's a docking station that looks like an actual Neo MVS unit, but isn't. What it does have is an HDMI output so that you can play those twenty games in a resolution that reveals all the blocky goodness of those old titles.
I'm most interested in that joystick. If it's a pin-for-pin substitute for the original Neo stick, and at least half the quality of the old hardware, then I'm getting ten of them.
