Retroarch Openbor Core Install May 2026
While OpenBOR is a popular engine for fan-made beat 'em ups, there is currently no official, widely supported "OpenBOR core" included in the standard RetroArch/Libretro core downloader. Because OpenBOR is a game engine rather than a single console emulator, every game is often tied to a specific build of the engine, making a universal "all-in-one" core difficult to maintain.
However, users often run OpenBOR within a RetroArch environment through specialized workarounds, particularly on specific hardware like the PlayStation Classic or Raspberry Pi. Common Installation Methods
Depending on your platform, you can "run" OpenBOR via RetroArch using these methods:
The PPSSPP Core Method (PlayStation Classic / PC)Some versions of OpenBOR were ported to the PSP. You can load these PSP versions of OpenBOR games using the Sony - PlayStation Portable (PPSSPP) core.
Install the PPSSPP core via the Online Updater in RetroArch.
Place your OpenBOR game folder (containing the .pak files) into your ROMs directory.
Launch the OpenBOR .elf or .pbp executable using the PPSSPP core.
RetroPie/Lakka Standalone IntegrationIn distributions like RetroPie or Lakka, OpenBOR often runs as a "standalone" port that is launched from the RetroArch interface rather than being a native .dll or .so core. Access the RetroPie Setup script. Navigate to Manage Packages > Manage Optional Packages. Select OpenBOR to install it. Place your .pak game files in the roms/openbor directory.
RetroDECK (Steam Deck / Linux)If you use the RetroDECK wrapper, you must follow a specific naming convention for detection: Extract the game to retrodeck/roms/openbor/. Rename the folder to

Option 2: The "PPSSPP" Workaround (Common for Handhelds/Lakka)

Download the PSP version of OpenBOR (usually a folder containing EBOOT.PBP or OPENBOR.PBP).
Place Games: Put your .pak game files into the Paks subfolder inside the OpenBOR directory. Launch:
In RetroArch, go to Load Core and select Sony - PlayStation Portable (PPSSPP). Select Load Content and navigate to your OPENBOR.PBP file. Option 3: Manual Core Installation (Advanced)
If you have a compiled .so (Linux/Android) or .dll (Windows) core file:
Go to Settings > Directory to find your Core folder location.
Use a file manager to manually move the core file into that folder.
Restart RetroArch, and the core should appear under Load Core. File Structure Requirements
For OpenBOR to recognize games correctly, ensure your folder structure looks like this: OpenBOR/ OpenBOR.exe (or .pbp for PSP core) Paks/ (This is where your .pak game files must live) Saves/ (Automatically created)
