# Quest Modding

# Preface

  • This guide is for both Quest 1 and Quest 2.
  • Nobody has yet been banned for modding.


By choosing to use mods, you understand that:

  • You may experience problems that don't exist in the vanilla game. 99.9% of bugs, crashes, and lag are due to mods.
  • Mods are subject to being broken by updates and that's normal - be patient and respectful when this happens, as modders are volunteers with real lives.
  • Beat Games aren't purposefully trying to break mods. They wish to work on the codebase and sometimes this breaks mods, but they are not out to kill mods.

Do not attack the game developers for issues related to mods, and vice versa - modders and game developers are two separate groups. Just don't be a jerk ok.

I watched a video tutorial on YouTube, but I got stuck/it didn't work. What gives?

We at BSMG strongly advise against using any video tutorials for modding. Often, we find that they are either outdated or contain incomplete, erroneous, or straight up incorrect information.

Instead, you should follow the written guides here on the wiki or seek out help in the BSMG Discord (opens new window).

# Installation

Currently the only recommended way to install custom songs and mods is BMBF sideloaded with SideQuest using a PC.

If you do not have access to a PC you can use an Android Phone or Tablet. Chromebooks and iOS devices such as iPhones or iPads are not supported.


Installing BMBF and modding your game will disable Official Multiplayer as well as viewing and uploading scores on the base game leaderboards. If you would like to play modded multiplayer, you need the mod, Beat Together, which allows for cross-play between pc and quest and allows for custom songs to be used. The mod can be found in the Beat Saber Modding Group in #quest-mods or on the Questboard (opens new window) site.

To get leaderboards on custom songs and to be able to get Performance Points (PP) from ranked songs you need the ScoreSaber (opens new window) mod. This link (opens new window) will take you to the ScoreSaber page to set it up. ScoreSaber does not replace the base game leaderboards, it only adds leaderboards for custom songs.

Note: Check the updates channel in the ScoreSaber Discord (opens new window) to see if the mod is available for the current game version.

# Installing BMBF with SideQuest

If you haven't already, download and setup SideQuest (opens new window).

There are three methods available to obtain BMBF:


If you've previously modded Beat Saber or have scores you want to backup, backup your Save Data first!

# Download from the SideQuest Store

  1. Connect your Quest to your PC, then go to BMBF On SideQuest (opens new window).
  2. Click the Install To Headset button. (Accept a prompt to open SideQuest if it appears.)
  3. Wait for BMBF to finish installing onto your headset.

Once installed, skip to the BMBF Setup section of the guide.

# Download the from the BMBF website

First download the BMBF APK (opens new window) on your PC.

Open SideQuest and connect your Quest to your PC.

If you have a modded game you also need to uninstall it by pressing the UNINSTALL APP button. You can later restore your save from the same menu, after modding.

Select the Install APK from folder button shown below and find the latest BMBF apk you downloaded and click on it, or simply drag the BMBF apk into SideQuest. Either method will install BMBF to your Quest.


You can now continue to the BMBF Setup section of the guide.

# BMBF Setup

Once it has been successfully installed, make sure you have the latest version of Beat Saber installed and unmodded.


Before modding, run Beat Saber once, play a level and immediately fail!

Modding currently does not work if the experimental multi-user feature is in use. You will need to temporarily remove all secondary accounts before modding the game. You can add them back later once you have installed your desired mods.

After running Beat Saber once, open BMBF from unknown sources as the picture below shows. UnknownSources

Once opened, follow each step in BMBF exactly as you're told to mod your game. Once completed, you should see QuestBoard (opens new window) with BeastSaber (opens new window) loaded inside of the BMBF app. This is where you can download any custom songs available. You can also click the BeatSaver button to download songs too.

If at any point during the install process you get the Restore App popup, just click Close. This warning is more directed to pirated versions of the game so if you're just modding there will likely be no consequences for ignoring it.


Continue to the Core Mods step of the installation process.

# Manage Save Data

# Backup Save Data using SideQuest

Open SideQuest and connect your Quest to your PC.

Navigate to sdcard/Android/data/com.beatgames.beatsaber/files using the SideQuest file explorer.

SideQuest Files

Save the files: AvatarData.dat, PlayerData.dat and settings.cfg into a folder on your PC. Do not lose these, as they contain your scores and other settings!

# Restoring Save Data using SideQuest

To restore your data, open SideQuest and connect your Quest to your PC.
Using the SideQuest file explorer, take the 3 files you saved from the Backup Save Data using SideQuest steps AvatarData.dat, PlayerData.dat and settings.cfg and put them in the sdcard/Android/data/com.beatgames.beatsaber/files folder.

# Installing Mods

# Core Mods

Before installing any additional mods look in the top right of the BMBF web interface, you should see a red button that says, Sync to Beat Saber. Click this and let it finish syncing. Then go to your mods tab in BMBF. Make sure that you have the 7 core mods:

  • Custom Types
  • Codegen
  • SongLoader
  • Playlist Manager
  • QuestUI
  • SongDownloader
  • PinkCore


Other mods will not work without these Core Mods!

If one of these mods are not listed, try the reinstall button in the Tools Tab inside of BMBF. If it still does not appear, or mods are appear but not working in-game, see Core Mods don't work for troubleshooting steps.

# Inside your Quest


Not all mods are available on QuestBoard!
If a mod is not seen in here, you should follow the Using Your PC method instead.

Open BMBF in your Quest and go to the Browser tab. The QuestBoard website should automatically open.
If not, click Choose Website at the top right, then click the QuestBoard button.


You should be greeted with the QuestBoard (opens new window) website below. Next, select the Get Mods tab.


Scroll down by clicking and dragging the pointer. You can now select any mod from the list, seen below, and download it by hitting the download button next to it. Some downloads may redirect you to a website or GitHub page. If so, follow the instructions onscreen, or select the latest .qmod in the Releases list, respectively.


# Using your PC

You can find and download other Quest mods from the BSMG Discord (opens new window) in the #quest-mods channel.


Make sure your Quest and PC are on the same network and that you are using http and not https!

Open BMBF in your Quest and go to the Tools tab, there you should see a web address and a version number similar to what's shown below.


On your PC, open your browser and type the address into the search bar.

You should be greeted with this screen below.

If this doesn't work click here for some troubleshooting steps.


Now just drag any Quest compatible mods into the upload box and sync. If the mod was originally made for an older version, then it won't automatically enable. To enable an old mod, go to the Mods tab and enable it from there.

# Installing Songs


Most maps in the "Top All", "Rating", "Downloads" or "Plays" sort filters were created before good mapping practices were established. Try downloading songs released between late 2019 and now to get the best custom levels experience.

# In-Game

You can now download songs in-game using SongDownloader (core mod) There are a few steps to downloading songs in-game:

  1. Open Beat Saber
  2. Go into Mod Settings (Settings -> Mod Settings)
  3. Open the SongDownloader tab
  4. Search for a song and download it.

When downloading songs in-game you do not have to restart the game. It automatically loads the song using the SongLoader. songdownloader

# Inside BMBF

There are 2 sources to getting custom maps inside your Quest using the browser window.

Both have a OneClick™ button that easily installs that song onto your Quest. You can switch between these websites using the globe icon in the top right of the browser window.

An easy way to download different kinds of songs is to use SyncSaber, which you can access by going into BMBF on your Quest and clicking the tab called SyncSaber. Here, you can download songs with a click of a button by choosing from different "settings". For example, you can download the top 20 songs in BeatSaver's (opens new window) "hot" section or the 50 hardest ranked songs.

Another method is using the Bookmark feature on BeastSaber (opens new window). After creating an account, you can click a little bookmark icon on a song and if you later delete all your songs from the Quest you can redownload the ones that are bookmarked with OneClick™.

# Using your PC

If you are unable to install songs inside your Quest, you can install maps using your computer similar to installing mods.

  1. Visit BeastSaber (opens new window) or BeatSaver (opens new window) on your computer
  2. Download the zip
  3. Follow the Installing mods using your PC steps up to the upload files screen.
  4. Drag and drop the map zip in, and it should be installed!

If the web interface doesn't load click here for some troubleshooting steps.


You can also download playlists in the same way. You can find various playlists on BeastSaber (opens new window) or various community discords. You can also make your own using BMBF Manager (opens new window) or Playlist Editor Pro (opens new window).

If you want to test a map you have created see the Testing on a Quest Section in the Mapping Wiki section for steps on packing it up for testing!

# Installing Models

Join the Qosmetics Community (opens new window) to change how your sabers, bloqs or walls look in-game!

# Troubleshooting

I watched a video tutorial on YouTube, but I got stuck/it didn't work. What gives?

We at BSMG strongly advise against using any video tutorials for modding. Often, we find that they are either outdated or contain incomplete, erroneous, or straight up incorrect information.

Instead, you should follow the written guides here on the wiki or seek out help in the BSMG Discord (opens new window).

# Adding mods from beatmods.com or models from modelsaber.com does not work

The reason adding mods from BeatMods (opens new window) or models from ModelSaber (opens new window) doesn't work is because those mods and models are for PC Only.

Get Quest compatible Mods from QuestBoard (opens new window) or #quest-mods in the Beat Saber Modding Group Discord, with Quest compatible sabers, bloqs, and walls in the Qosmetics Community (opens new window). Once you have your mod or model qmod use the BMBF Web Interface to install it.

# Sideloading BMBF failed

When sideloading BMBF you get the error INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.weloveoculus.BMBF signatures do not match the previously installed version; ignoring!

You will need to uninstall the BMBF version on your Quest. You can do this from SideQuest's My Apps menu.

# Core mods don't work

If you are having problems with core mods, please verify that you are not trying to use any outdated mods. Any mod made for a previous game version is considered outdated. Once you have removed them:

  1. Go to Tools
  2. Click Delete Mods
  3. Click Sync to Beat Saber

If you had mods installed before this, turn them off then on again to reinstall them.

# BMBF web interface not loading

If your BMBF Web Interface is not loading, be sure that you're typing the IP from the tools tab into your browser on your computer that's on the same network. Make sure that:

  1. Your IP is not, if that shows up try rebooting your headset and/or router.
  2. BMBF is open in the headset
  3. There is http:// at the beginning of the link, not https://
  4. You have :50000 at the end of your link
  5. Your PC and Quest are on the same wifi network
  6. Your IP is hasn't changed as it changes from time to time

If none of these work, restart your Quest and go through the list again.

# BMBF not loading configuration after a few minutes

This is likely due to using BMBF on a game version it was not built for. Such as using BMBF for Beat Saber version 1.13.0 when the version of the game installed on the headset is 1.12.2.
If the game version matches what the BMBF release page says its built for, try restarting your headset. If it still does not work use the BMBF Web Interface and click Quick Fix in the Tools tab.

# Beat Saber is black when I launch it

Open the library on your Quest. Click the three dots next to Beat Saber and then click Permissions. In the menu that pops up, enable storage permissions and try launching the game again.

# My Sabers and Mods wont enable/work

This is most likely due to having an outdated BMBF App, grab the latest BMBF Release (opens new window). If the BMBF version for your Beat Saber is not there then please wait a while for the unicorns to update BMBF.

  • If your level doesn't load then try installing mapping extensions from #quest-mods. It may also require the mod Noodle Extensions which isn't on Quest yet.
  • If your BMBF is on the latest version and mods wont be enabled in game, uninstall Beat Saber with the uninstall BS button in the BMBF Tools tab then reinstall and remod.
  • In very very very rare cases, BMBF does not have file permissions to copy mods into the right location. Check in SideQuest to make sure BMBF has file permissions.

# Beat Saber is crashing

If your game is crashing when doing something, disable your mods one by one, running your game each time to see if the issue is fixed before asking for help in a support channel.

# I only see a white screen when I open BMBF

If you only see a white screen when you open BMBF from unknown sources, try waiting a few secconds. If that does not work, restart your quest and try opening BMBF again.

# My Beat Saber gets 3 dots when I launch

If your Beat Saber is getting 3 dots when launching make sure that:

  1. You launched and played one song before modding the game
  2. You're not using a pirated version of the game
  3. Make sure you're using the latest version of BMBF
