Super Mario Flash is a Flash game that appears to be based off of Super Mario All-Stars, using the map feature from Super Mario Bros. 3 and the level designs from Super Mario Bros. and Super Mario World. While it may not play exactly like the games it's based off of, the game served as a passable substitute for those in the mid-2000s who had Internet but didn't have the resources to play the original games.
In this run, Vexxter, TheAmazingYucemu, and RileyTech use a variety of glitches, some of which you can't find in the original games, to beat the game as fast as possible.
