Question for non-Finale scores

[Sean081799]

Hey everyone, I recently made a solo piano arrangement for Mt. Thunder from Pokemon Mystery Dungeon Red and Blue Rescue Team, but I used MuseScore2 instead of Finale, so I don't have .mus files and such. Is there a way to either submit a non-Finale score or an alternative file (or if anyone knows how to convert a .mcsz file to a .mus file safely)? I do have a PDF file good to go though.

And yes if you are asking this is my first arrangement of any piece from any game, and I know it isn't the best possible arrangement.

Finale Notepad is a free download, with which you can save it as a .mus. To get the musescore file into Finale, you'd export the Musescore file as an .xml and then import it into Notepad, and then save it as .mus.
