http://www.explodingrabbit.com/games/super-mario-bros-crossoverI played it for like 30min now and all i have to say is...AWSOME. I really like it.
There are many many features like
*) difference skins (Mario Nes, Mario 2 on GB, Mario World Snes, Mario Bros 3, Demon)
*) many playable Characters like Simon Belmont, Trevor Belmont, Ryu (Ninja Gaiden), Mega Man, and many more
*) Cheats to Unlock
*) playable with Keyboard or Gamepad (but u need a little Programm for using ur gamepad)
*) 5 difficults(very easy, easy, normal, hard, very hard)
*) 3 modes like Survival
*) u can save ur game
I looked thru the sites but didnt see any Topic of the game. Hope u will enyjo it as much as i do.
