I've spoken to a few people that played Link's Awakening on the Gameboy and most people remember the same thing as me, the music - The ending theme in particular.
I used to beat the end boss over and over again just to listen to the end credits - It's the best rendition of the 'Zelda theme' (Overworld theme I guess!)
I also really hope they do a version of the song in, I really have no idea how I remember this, but, Richard's Villa, it was a rendition of for the frog the bell tolls from The Prince's Adventure.
Anywho, it's been almost 25 years since I played it and even had a gameboy, never had chance to play it in colour either which I wish I did. I've genuienly not been this excited about a game since Quake 3.
