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.
In this TAS, TwistedTammer goes through the entire game collecting all the permanent inventory items, which includes heart pieces, L2 upgrades, capacity upgrades, photographs, and the colored tunic upgrade exclusive to the DX version of the game. However this run does avoid some major glitches in order to make the viewing experience more enjoyable.
