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 without making use of the warpzones, yet still creating the best and fastest possible route. This run also beats MarioUniverseZone's effort by almost two minutes.
