If you're talking about a Super Smash bros. style game, there was a creator on the japanese community who something similar. I have the game he created but I'm not sure if I can just re-distribute the download code of it.

It's a Japanese program that looks very similar to SSB. I haven't quite figured out how to play it, as it seems to not have a smash attack equivalent, but it's still fun to mess around with!
