Retroarch Openbor Core

If you grew up in the arcades of the 90s, titles like Streets of Rage, Final Fight, and Double Dragon hold a special place in your heart. But what if I told you there is a whole universe of unofficial sequels, crossovers, and brand-new beat ‘em ups that rival the classics?

Enter OpenBOR—and yes, you can now run it directly inside RetroArch.

For years, OpenBOR was the "lonely engine." You kept a separate .exe file on your desktop or wrestled with standalone Android ports. But thanks to the Libretro team, the OpenBOR core has matured into a stable, unified way to play thousands of community-made beat ‘em ups.

Here is everything you need to know to get it running.

If you experience slowdown on a low-powered device (like a Raspberry Pi 2 or an old Android phone):

The RetroArch OpenBOR core is a "B-tier" core for an "S-tier" engine. It works 90% of the time. When it works, it is magical. When it fails, it is usually due to a poorly coded .pak file or a case-sensitive folder name.

If you have a collection of OpenBOR games collecting dust on your hard drive, ditch the standalone launcher. Consolidate your library into RetroArch. Your ultimate beat ‘em up arcade is waiting.
