The Legend of Zelda: Link's Awakening DX is an updated version of an older GB game which adds color, an additional dungeon, various other minor features, and a lot of bug fixes. Link, after rescuing Hyrule (again?), sets off on a journey and subsequently shipwrecks on the mysterious Koholint Island, which has been overtaken by evil monsters which he must defeat in order to find a way back home.
Through a wide variety of glitches and general optimizations, this is now almost ten minutes faster than the previous full run of this game.
This run does not make use of a form of warp glitching, but still demonstrates that they obviously didn't fix as many bugs as they thought.
This movie has a full Atlas Map encode, which shows the standard encode overlaid on a zoomed out map.
