super mario bros was a great game but for the better players in mario bros,
you shoud get the switch edition of the game and speed run it.

rules
warps and warpless is aloud
if you are new i dont recommend this game
switch is requried

dear mods what do you think about this

A leaderboard already exists for that game, did you not search for it?

I suggest propose your request on that leaderboard's forums. We won't add it here because it's a different game.
