It's Super Mario Bros 1, but you can play with Samus Aran, Mega Man, Link, Contra Guy, or Simon Belmont - with the correct music and weapons. It's pretty damn sweet.

This guy is gonna be big. INTERNET big.

 

I gave this a spin and thought it was amazing. Link jumping was odd considering the first game, and Samus ran weird. Never played it on the NES. Other that that it was was great. They handled the power-ups, mushrooms, excellently.

 

Also got hit with it today. This is will be massive from this.

 

Ever heard of Mushroom Kingdom Fusion?
