This is a romhack of the original sup3r m4rio br0th3rs. It was one of the first romhacks I completed, and I was just learning how to use Tile Layer Pro. It seemed like a worthy cause at the time. Screenshots are from version 1.0, which is no longer available.
However, you can download version 2.0 here.
I was really lazy in 2005, when I made this hack, and I just changed the sprites for M. into Block, which caused all of the text in the game to get messed up, yet remain barely readable. I grew to like the effect a little, made the game seem even stranger--like some Russian pirate cart.
Check out this super de-make in these screenshots:
