I just finished an arrangement of Dedede's Royal Payback from Kirby Triple Deluxe, which has one of my favorite video game OSTs, and I'm happy that I'm finally getting around to transposing it. I'm all but ready to submit the arrangement, however, I use Musescore, and as such don't know how I would go about getting a .mus file for my submission. Is there any way to convert the sheets other than remaking them entirely?
