I guess I'll contribute something to this community. This is a romhack of The Legend of Zelda Link's Awakening DX V1.2 (USA) on the Game Boy Color. I removed a lot of collision from the game so people can enter entrances from the back. Tell me what you discover when you do that! Download in Spoiler:
Tools used: LALE (Link's Awakening Level Editor) - It only works on Link's Awakening DX V1.2 (USA) (You can also edit the 3DS VC version of the game with this since it's the same game with separate patches.)
(if you don't want the prepatched game, then download the patch instead that's attached and use beat to patch it.)
