Just watch the video. http://mirror0.fuzzy2.com/namikai/20050816173016/deco_x_sun_high.lzh Not a real game, but that is very impressive.
Hehe, saw this on insertcredit about a month back. It's pretty odd being able to identify some of the characters from gaming in my childhood. It's also a bit embarrassing that I don't recognize over half of them. -_-
I was very impressed that a couple of guys just decided to make this video. It's certainly very professional. Now if they actually coded the game I'd be blown away. There's so many talented people out there in the world that should be let loose with proper dev hardware to create their own games. Like back in the day of 'bedroom coding' on the Speccy or C64.
