Guide for APK Downgrader - Web
First of the question: What am I downloading from the Patches section?
You are downloading a binary difference between the purchased unmodified Beat Saber version you have and the unmodified Beat Saber Version you want to downgrade too.
Stored in those files is how to rearrange the bytes of the APK so it'll be the older version.
So is this piracy?
No. You're not downloading any game code. Those patches will only work (aka give you a downgraded APK) if they get used with a legally purchased version of Beat Saber
