Getting OpenBOR (Open Beats of Rage) running inside RetroArch can be a bit of a "quest" because there isn't a standard, one-click official core in the main downloader for every platform. Instead, most users run it as a standalone engine or through a workaround like the PPSSPP (PSP) core.

Here is a featured guide on how to handle the installation and setup for your beat-'em-up library. The "Workaround" Method: Using the PPSSPP Core

Since a dedicated OpenBOR core is often missing from the standard RetroArch Online Updater, many enthusiasts use the PSP version of OpenBOR running inside the PPSSPP core.

Download the OpenBOR PSP Build: Look for an OpenBOR distribution that includes a PSP folder. Inside, you should find a file typically named EBOOT.PBP (sometimes renamed to OPENBOR.PBP).

Add Your Games: Place your .pak game files into the Paks folder within the same directory as the .PBP file. Load in RetroArch:

Open RetroArch and go to Load Core > Download a Core > Sony - PlayStation Portable (PPSSPP). The Ultimate Guide to the RetroArch OpenBOR Core:

Go to Load Content, navigate to your OPENBOR.PBP file, and select it. The "Native" Method: RetroPie & Batocera

If you are using a dedicated gaming OS like RetroPie or Batocera, OpenBOR is often available as an "experimental" or "optional" package rather than a standard RetroArch core. For RetroPie:

Navigate to RetroPie Setup > Manage Packages > Manage Experimental Packages.

Find openbor (often listed near entry #342) and select Install from Source.

Once installed, you can drop your .bor folders or .pak files into the /home/pi/RetroPie/roms/ports/openbor directory. Critical Setup Tips

Version Matching: OpenBOR is a game engine, not just a simple emulator. Many "Mods" (games) are built for specific versions of the engine. If a game crashes, it’s likely due to a version mismatch between the engine and the .pak file. Visit the Libretro Buildbot (official build repository) or

File Naming: When using systems like RetroDECK, ensure your game folders end in .bor or .openbor and contain a text file with the exact same name as the folder to help the system "see" the game.

Missing Core Downloader: If you can't see the option to download cores, go to Settings > User Interface > Menu Item Availability and enable the Core Downloader. RetroArch Simple Setup Guide

This guide covers how to install the OpenBOR core on RetroArch.

Important Note: The OpenBOR core is available on PC (Windows, Linux, macOS) and Android. It is generally not available on consoles (Switch, PS Vita, PSP, Xbox) due to the high processing power required for many OpenBOR mods.

Step 5: Configure Controls

OpenBOR games often expect a standard arcade layout:

To remap:

  1. Launch any OpenBOR game.
  2. Open Quick Menu (F1) → Controls.
  3. Remap as needed, then Save Core Remap File (or Game Remap).

Method 4: macOS Installation

  1. Open RetroArch.
  2. Go to Online Updater > Core Updater.
  3. Find and select OpenBOR.
  4. The core will install as a .dylib file.
  5. Note for Apple Silicon (M1/M2/M3): The core runs under Rosetta 2 if you are using the x86_64 build of RetroArch. Native ARM cores are in development but not yet universal.

Method 1: Installing via Online Updater (If Available)

  1. Open RetroArch.
  2. Go to Main Menu → Load Core → Download a Core.
  3. Scroll down until you find “OpenBOR” (may be listed under “Game engines” or “Experimental”).
  4. Select it to download and install.
  5. Once installed, you will see “OpenBOR” in your core list.

Step 3: Launching a Game

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.

  1. Open RetroArch.
  2. Select Load Core.
  3. Select OpenBOR.
  4. Select Start Core.
    • If you have placed games correctly, the OpenBOR menu should appear.
    • Use the on-screen menu to select which mod you want to play.

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.
