LodorOS

Your RomM library, in your pocket. LodorOS is a MinUI fork that turns a cheap retro handheld into a thin client for your self-hosted RomM server — browse your whole collection offline, download a game on demand, and have your saves sync both ways automatically around every play session.

You keep your ROMs and saves on your server. The handheld holds only what you're playing. Wi-Fi-dark by default, sync when it can.

What it does

• Whole-library browsing offline — every game in your RomM collection appears in the menu as a lightweight stub, with box art, even when the device is offline.
• Download-on-launch — pick a game you don't have yet; it downloads, verifies, and boots.
• Two-way save sync — saves pull before you play and push after you quit, to RomM, automatically. Restore an older save from the server any time.
• Private by design — reach your server over Tailscale (a private tunnel, works anywhere) or Cloudflare Access (a service-token'd public endpoint) — your RomM is never exposed on the open internet.
• One release, every device — the same download boots the whole supported fleet; each device reads its own platform folder.
