Awesome!

There is a leaderboard for that - it's in Multiple Classic Mario Games. https://www.speedrun.com/mcmg#Super_Marihour

the rules say -Memfiles, warps, inventory editing, and any other functions may be used to set up your file and to reset between attempts. -During actual IL gameplay, no practice rom functionality may be used. For example, no cheats, no visible menus or displays, of course no macros, etc.
