Here it is.
ALL 14 COLLECTIONS!
I know some items depends on the user, but this has almost every item in game with the collection completion outfits, which I believe matter the most. It has the squirrel, robot, and shark body types as well.
However, Soccer and Volleyball are the only things that aren't pro. Bowling is at B rank. Tennis, Badminton, and Chambara are at E.
If we wanna share the file around and have someone rank up the sports one at a time, we should use this save as it has all of the collections available so far.
