Use turbo mode (press shift key and green flag at the same time) I did a noteblock cover of the Mii Channel theme. I didn't do the full song because I kinda got tired. Any hate comments will be deleted. It slows down in a few parts. Sorry :(
I used some online sheet music for this. Here's the link: https://musescore.com/pimplup/mii-channel No, I did not arrange the sheet music, so the credit goes to the person who did.
