First Boot Checklist

Use this checklist the first time REG Linux boots on a new device. It is intentionally short, so you can finish setup fast and get to playing.

Before you power on

  • Use the device-specific page in the Devices section to confirm any quirks or firmware notes.
  • Make sure the image was flashed cleanly and the storage media is reliable.
  • If you plan to use Wi-Fi, have your network name and password ready.

During first boot

  • Let the system finish its initial setup. The first boot can take longer while storage is prepared.
  • Keep the device powered and avoid removing the storage media until you reach the main menu.
  • When prompted, map a controller. If the prompt does not appear, see Controller setup.

Quick setup tasks

  • Set language, time zone, and regional format in the system settings.
  • Connect to the network (Ethernet or Wi-Fi) so updates and metadata downloads can work.
  • Confirm audio and display output are correct (volume, resolution, rotation).

Add your content

  • ROMs: copy to /userdata/roms/ using USB, network share, or SSH.
  • BIOS files: copy to /userdata/bios/ as required by each system.
  • If you are unsure which systems are supported, start with Emulated systems.
