Beat Saber has a Party Mode, which as the name implies, is great for parties. One issue I have with it is that it stores the best 10 highscores, regardless of who obtained that highscore. So, if the best player plays a map 10 times, all the other players' highscores are gone. Personally I’d much rather have it only remember each player’s highest score.
BeatStripper runs outside of BeatSaber and removes all but the highest score of each player from the Party Mode scores. Just run the executable, and it should find the score file and update it.
As a bonus, it also capitalises the player names.
Just extract the ZIP and run
If you have any problems with it, please let me know on the GitLab project page.
