lol Its really easy to hack the NES version of Mario, though, so I bet something similar maybe could come out in some pointless flash game. Did you ever see the one where M. Bison beats the first level of Mario by simply dashing across the map and blowing everything up? That was cool.
Ah, so it was made with M.U.G.E.N. I messed with it for a little while, but got lost and never understood how to make the box bigger or add custom fighters. I might go back into a bit, but apparantly everyone hates it because of the community, so it might be hard to get help.
