I did one as a request (the 8am tune) but enjoyed it so much I did 3 more in the past few days, and I feel like doing more. I do all of these by ear ~ Listening to the originals and then writing my own version.
In order of creation ~
8am - The 8am theme music, I remember this catching in my head when I used to play AC/GC
<-- see what i did there~Save Game - The pretty tune that plays when you're being a good person and saving your game instead of resetting / powering off.
Title Screen - A pain in the prostate to transcribe by ear, no thanks to the pretty elusive piano samples used in the actual game. I think I got the piano close enough. Except for the ending (just before it goes to loop round) since the actual version fades out.
9PM - 8PM/9PM were my most popular playing times for AC, so these two tunes definately stick in my head. I deviated pretty far from the original instrument wise, though still stayed pretty close as for notes. Maybe I'll go crazy on another one I'll do sometime.
8PM ~Arranged - My arrangement of the originally pretty simple 8PM theme.
Working For Nook - Working for Tom Nook =D
THAT'S IT FOR NOW.
