Mario Mafia 2 is a Super Mario Bros. ROM Hack by JGW in 2006 that "adds a whole new challenge world" to the game. Gameplay components from The Lost Levels, such as wind and timer depleting at the end of castle levels, are included in the hack for a little zing.
My TAS beats the game in the fastest amount of time possible as Mario, utilizing warps present in the game to create the best and fastest possible route.

If I'm reading this correctly, this is, so far, the only run of this hack that uses warps throughout.
