The most common way to play OpenBOR games through RetroArch—especially for setups—is by using the PPSSPP (PSP) core as a wrapper. 1. Preparing Your Portable Environment
If you haven't already, download the "portable" or "standalone" version of RetroArch from the official website and extract it to your chosen portable drive. This ensures all configuration files stay within that folder, making it truly mobile. 2. Download and Install the OpenBOR Core
The OpenBOR core looks for a Paks folder inside the system/openbor/ directory. It will not scan your ROMs folder by default.
