Raspberry Pi Micro SD & USB 3 Flash Drive

Batocera Linux for raspberry Pi 3 model B/B+ and Pi 4 Model B is installed on the micro SD card. Your games and digital media are stored on the USB 3 flash drive. By separating the operating system and media allows for fast recovery in the event of a corrupted system. You can also delete and add any new media without having to rewrite the entire micro SD card as all roms are stored on the separate USB 3 flash drive.
