EXTRACT EVERYTHING BEFORE RUNNING ANYTHING
BSLegacyLauncher is a program designed to fetch any version of Beat Saber from Steam's depots, and launch it within the same program! You do not need to move it to your Steam directory, as your current installation will remain untouched! So if you ever want to switch between two versions, this is the program for you!
This utility was created by RiskiVR & DDAkebono & ComputerElite.

Why does it need my Steam login info?
Our utilities depends on Steam's open-source Depotdownloader for authorization to connect to their official servers. You must have legally purchased the game, since we don't condone the piracy of Beat Saber. The files downloaded with the tool come from Steam's manifests. Our tool is just a bridge connecting between you and Steam. Your info is safe and secure, it does not go anywhere else.
Why is the Console App Utility not opening or closing immediately after trying to start?
This issue can one of many reasons. After my research on the issue, I have found these possible reasons why and how to fix them:
- Windows File System may have a corruption within itself internally. Fix: Re-install Windows
- Windows doesn't have necessary files to run application. Fix: Run any updates that may be waiting for you, this includes any Feature updates past Windows 1903 and on. Plus make sure you have the .NET Runtime v3.1.0+ installed
- Upon extracting the files, your system might have marked the package as "unsafe". Fix: Right click the main

folder, go to "Properties", and unblock all files. Your anti-virus may be blocking the app, Refer to your anti-virus program manual on how to add an exclusion to (an) entire folder(s) - Windows 7 or 8 or 8.1 might straight up not run the application, let alone SteamVR. Fix: Just upgrade to Windows 10 already
Quest: I downgraded, but BMBF isn't modding the game.
Follow these steps to ensure things will work properly
- Download BMBF for 1.13.2 fresh from the stable release section of the BMBF website.
- Uninstall both Beat Saber and BMBF via Side Quest
- Restart the Quest, an important step, honesty
- Put your downgraded game and BMBF on your Quest one last time.
- Open the game, play a song, then mod with BMBF
Quest: I downgraded my game, but when I boot it up, it's still the most recent version.
This is due to one of three things:
- You never deleted Beat Saber from your Quest before trying to install your downgraded game, and either you didn't get any message from Side Quest at all, or you missed the error message.
- You did get a successful apk install message from Side Quest, but you installed the apk out of the BSBackups folder in error. Please note the apk in the BSBackups folder is just the unmodified original backup you made.
- You stepped away from your Quest for too long after installing the downgraded game, and the proper inactivity period passed in order for the Quest to automatically update.
