Installing the OpenBOR (Open Beats of Rage) core in RetroArch allows you to play a massive library of fan-made beat 'em ups and side-scrolling action games. Because OpenBOR isn't always available in the standard "Online Updater," the setup can vary depending on your platform. 1. Check for the Core (The Easy Way)
First, see if the core is already hosted for your specific device: Open RetroArch. Go to Main Menu > Online Updater > Core Downloader. Scroll down to OpenBOR.
Note: If you don't see it, your platform (like some Windows builds or specific consoles) may require a manual install. 2. Manual Installation (If not in the Downloader)
If the core is missing from the list, you will need to find the .dll (Windows), .so (Linux/Android), or .dylib (Mac) file for the OpenBOR core.
Download the Core: Look for the "OpenBOR Libretro" core on the official Libretro buildbot or community forums like Libretro Docs.
Place the File: Copy the core file into your RetroArch cores directory. Typical path: RetroArch/cores/ 3. Setting Up Game Files (.PAK)
OpenBOR games come as .pak files. RetroArch needs these organized in a specific way to read them correctly.
Create a folder named OpenBOR inside your RetroArch system directory: RetroArch/system/OpenBOR/ Inside that folder, create a subfolder named Paks: RetroArch/system/OpenBOR/Paks/ Place your game .pak files into that Paks folder. 4. Running the Games Once your files are in place: Go to Main Menu > Load Content. Navigate to your system/OpenBOR/Paks/ folder. Select your game's .pak file. Choose OpenBOR as the core. 5. Troubleshooting & Performance
Naming Conventions: Some versions of the core require the .pak files to be named in lowercase or have no spaces. If a game won't launch, try renaming My Game.pak to mygame.pak.
Extracting Data: If a .pak file fails to load, some users have success by extracting the .pak (using OpenBOR extraction tools) into a folder and pointing RetroArch to the data folder, though the single .pak method is the standard for the Libretro core.
Control Mapping: OpenBOR games often have their own internal menus. If your controller isn't responding correctly, use the RetroArch Quick Menu (F1 or Command + Menu) > Controls to remap the inputs.

Installing the (Open Beats of Rage) core in is a non-traditional process compared to standard console emulators because OpenBOR is technically a standalone engine rather than a single-console emulator. As of April 2026, it is important to note that a native OpenBOR libretro core is not available in the standard RetroArch Online Updater for most platforms.
Instead, users typically run OpenBOR content through a "wrapper" core—most commonly the core—or by using specialized custom builds like RetroArch Xtreme 1. The Wrapper Method (PPSSPP Core)

OpenBOR operates differently than standard console emulators. It requires a specific folder structure to recognize games (PAK files).
System Directory: Ensure your RetroArch "System" folder is correctly mapped in Settings > Folders.
The OpenBOR Folder: Inside your RetroArch /system/ folder, create a directory named OpenBOR.
Paks Folder: Inside /system/OpenBOR/, create a folder named Paks.

If the core fails to load or crashes upon startup, check the following variables:
File Names: Ensure .pak files do not have special characters or excessively long names.
Core Compatibility: Some older OpenBOR games (designed for versions 2.x or 3.x) may have compatibility issues with the latest Libretro core.
Video Driver: If you get a black screen, try switching your Video Driver (Settings > Drivers > Video) between Vulkan and GL. Are you getting a specific error message?

Note: If you don’t see it, update your Core Info Files and Assets first via Online Updater.

|---------|----------|
| Core crashes on load | Make sure your .pak file is not corrupted. Test it in standalone OpenBOR first. |
| Core doesn’t appear after manual install | Ensure the file is named exactly openbor_libretro.dll (or equivalent) and that you’ve updated core info files. |
| Controller not working | OpenBOR games often expect specific input types. Use Quick Menu → Controls → Port 1 Controls → Set “Device Type” to “RetroPad with Analog”. |
| No sound | Check RetroArch’s audio driver (Settings → Audio → Output). Switch between xaudio and wasapi on Windows. |
Unlike standard RetroArch cores (like NES or SNES), OpenBOR does not use standard "Load Content" for individual files. You generally point the core to the game folder.
Alternative Method (Windows/Linux/macOS):
You can also try "Load Content", navigate to your roms/OpenBOR folder, select a specific game folder, and select Open. However, using Start Core is the most reliable method for OpenBOR.
If you are a creator, you can test your own OpenBOR builds directly in RetroArch without repackaging.
MyGame/)..PAK yet.levels.txt or data/ folder.When finished, pack the folder into a .PAK using the packer.exe included with the OpenBOR tools.
The OpenBOR core is not available through RetroArch’s default online updater in most stable builds. You must manually download or build the core. However, recent experimental/nightly builds of RetroArch for Windows, Linux, and Android include the core in their online updater. Check your “Load Core” → “Download a Core” list first.
RetroArch expects OpenBOR games in a specific folder:
RetroArch/

└── openbor/
└── Paks/ ← place .pak files here
If Paks folder doesn’t exist, create it.
Alternative: Some cores let you load
.pakfrom anywhere. Try Load Content → select.pak→ choose OpenBOR core.
