Super Mario Bros. 3 is a very famous and popular game for the NES. There are normally two main ways to beat it: the quick way using warp whistles to skip worlds, and the longer way which goes through all the worlds.

Lord_Tom goes the same route as the this game end glitch run. However, he achieves total control of the game, pushing the run to a whole new level. He gives himself new powers, like the speed booster and the suit-swap, to name a few. Read the author's comments for more details.

This run was shown at Awesome Games Done Quick 2016 during the TAS block. You can see it here

WARNING: Mario's new powers in this run include flashing lights which may cause epileptic seizures to those affected.
