Retroarch Openbor Core ((full)) Official
The Ultimate Guide to the OpenBOR Core in RetroArch If you grew up in the arcades during the 90s, you likely have a soft spot for the "Beat 'em Up" genre. From Final Fight to Streets of Rage , these games defined a generation. While official commercial releases of these games have slowed down, the homebrew community has kept the spirit alive through OpenBOR . OpenBOR is the premier engine for creating custom beat 'em ups. While it is traditionally run as a standalone application on Windows, the RetroArch OpenBOR Core (often utilizing a port known as Beetle OpenBOR or similar variants) allows you to bring these massive, fan-made brawlers to consoles, handhelds, and your main living room setup. Here is everything you need to know about getting OpenBOR running inside RetroArch.
What is OpenBOR? OpenBOR stands for "Open Beats of Rage." It is an open-source engine designed specifically for 2D scrolling fighting games. It is not an emulator; it does not play ROMs from an SNES or Sega Genesis cartridge. Instead, it runs PAK files . These are custom game packages built by community developers. Over the years, the engine has evolved to support high-resolution sprites, complex scripting, and gameplay mechanics far beyond what the Sega Genesis could ever handle. Famous OpenBOR Games Include:
Streets of Rage Remake (A massive reimagining of the SoR series) Teenage Mutant Ninja Turtles: Rescue-Palooza! Crime Fighters: The Last Stand Marvel Infinity War Hyper Final Fight

Cross-Platform Portability: If you are running RetroArch on a PlayStation Classic, a Raspberry Pi, an Android phone, or a Nintendo Switch (via homebrew), the standalone PC version won't work for you. The core allows these devices to run OpenBOR games. Unified Controls: RetroArch handles the controller mapping. You don't have to configure joysticks inside the OpenBOR menu; RetroArch translates your inputs automatically. Shaders and Overlays: You can apply RetroArch CRT shaders or LCD overlays to give these modern homebrew games a classic arcade aesthetic.

Step 2: Prepare Your Games (The PAK Files) OpenBOR games usually come in ZIP or RAR archives when you download them from homebrew sites. You cannot load these archives directly into RetroArch. You must extract them.
Download your desired OpenBOR game. Extract the archive using 7-Zip or WinRAR. Look for the game file. It will usually be a .pak file. Sometimes it is named bor.pak , data.pak , or specifically named after the game. Create a folder for your OpenBOR games (e.g., RetroArch/roms/OpenBOR/ ). Crucial Step: For the best results, keep the .pak file inside its own subfolder, or ensure the core can find the path. Unlike a Mario ROM, OpenBOR games often require other asset folders (like data or levels ) to be present alongside the PAK file.
