Rhythm Sprout - Trophy/Achievement Exploit Guide (Spoilers)
6Update: Version 1.000.001 removes this. If you have the unpatched game, or figure out how to download it without the patch, this will work.
Every skilled based trophy in Rhythm Sprout can be earned by simply pushing R3 during the level. This will activate an auto play mode where the game will hit every mark perfectly, which guarantees the CD on every level besides 13, and 14. These levels still work with the exploit, they just don't offer enough points outside of finishers to earn the score needed. By simply pushing random inputs you should earn enough points to complete these stages as well.
While I listed this as a trophy/achievement guide, I unfortunately can not confirm it works on any platform besides PlayStation 5. The PlayStation 4 version does not work on PlayStation 5, but my girlfriend confirmed she was unable to do it on her system. If others want to try I wish them luck. I also don't know about how this works Xbox side, though I would love for someone to test it out.
Finally, I'm sorry if picking the optional boss stage is too big of a spoiler. It's what I consider the hardest stage to do legitimately, which made it the best example to use in the event you wanted to watch the video. I can also confirm this can be used to unlock every skill based trophy. There are three I was not able to unlock, I think they're glitched, but we will see once more people have a copy.
