Had to look up what this even was but then when I saw a pic I was like "OOOH THOSE THINGS!"

A store in a neighboring county had two... one with some old Namco games and another with three versions of Street Fighter II, including Super Turbo (which never had a *good* home port). I was legitimately interested in the SFII one, but I didn't have the money or means of transport at the time.

Thanks for reminding me of these. Now I know what to save for.

Looking into what others these guys did.

Actually... one question I had when I first saw these is how do they work? Surely they're some sort of emulation, right?
