Super Mario All-Stars is a collection of four remakes of Super Mario Bros., SMB: The Lost Levels, Super Mario Bros. 2 and Super Mario Bros. 3. It features enhanced graphics and audio thanks to the more powerful SNES hardware. It also features a save feature, which was absent in the original games.
IgorOliveira66X utilizes debug code (a feature usually used by developers to test the game) that allows Mario to freely roam the level, gaining invincibility and the ability to cycle between powerups and suits. It even allows to pause or advance the game by one frame. This run also showcases glitches present in this particular version of Super Mario Bros. 3 while using the debug code, from clipping through blocks to glitchy pipe transitions, including glitched palettes and more creative ways to die in a level.
