Just like music
I'd been wanting to play the option music from Mario Kart D-D, but the old keyboard didn't work so I kept running upstairs and downstairs from the game to the piano trying to right down the notes. It didn't work out. I was more recently, at school, was able to find low quality MP3s from the game and was able to make 1 midi. I also started on Bowser's Castle, but it was so hard to make out different instrument parts, I gave up, but I partially accomplished my goal. I printed out the notes to the piano track and wrote in the repeated bassline that I'll probably have to change for the piano arrangement. My plug's still busted.

Scribbled out is the word "untitled"
I submitted the midi to vgmusic.com. I'm the first to do that game I think. Since it IS the VG Music Archive, it won't be posted for months. I uploaded it
here, but it may not play for some reason. I screwed up the "new age" track so bad. It was hard to disect.
