These are music and no music downloads for the deterministic patch of the game, where the screen-scrolling tweener is bound to 31fps frame timing instead of inconsistent system timing. You can read more about what problems this solves here: https://www.speedrun.com/redball1/news/246
As long as the .swf files are not renamed, they will still work with the autosplitter. If you are using this deterministic patch, please indicate so in the variable inputs of your run submissions.
