Portable RetroArch refers to configuring the popular open-source emulator frontend so that it runs entirely off a removable storage device (like a USB flash drive or external SSD) without installing files on the host computer. This allows you to carry your entire classic gaming library, custom emulator setups, save files, and controller mappings in your pocket and play them on any compatible PC. Key Benefits of a Portable Setup
Zero Host footprint: It requires no system installation, registry changes, or admin privileges on the guest PC.
Unified Save Files: Your game progress, states, and memory card files stay on the drive, eliminating the need to sync across multiple computers.
Configured Once: Features like custom shaders, cheats, and button configurations carry over to any machine you plug into. How to Create a Portable RetroArch Drive (Windows)
