At it's core it's a system for organizing and displaying your collection of retro games (ROMs). Instead of navigating through folders or manually moving games from a hard drive to whatever system you want to play on, you can load them into RomM, navigate to the app and download them from the browser.

You can share it with your friends so they can access your library, use the plugins to download games directly onto some platforms (without a browser), or play older systems in the browser for a quick session.

At some point we'd like to handle save file sync between devices so you can stop playing on one device and pick up where you left off on another!

I saw this project some months ago and it looks awesome, just haven't set it up yet.

How does it handle modern games? I have a lot of DRM free games and small indie projects I've collected/archived and I want a way to neatly display them and download them

You can display almost anything pretty well. For DRM free games, just upload them as a zip or put them in your library as a folder with everything inside and RomM will display them as everything else. You can do it under the "win" folder so RomM knows those are PC games

Awesome! I also see RuffleRS is supported too for flash archiving. I'm jumping on this now

Is there anyword on integration with Batocera, ES-DE, or Retroarch? Those mega systems would get supercharged with it. The homelab community would likely catch on very quick.

Right now we have a playnite plugin, a muOS/portmaster app and a on-going decky plugin for steam deck. We have plans to integrate with RetroDeck. No luck with Retroarch since it doesn't support plugins, but you can always use something like syncthing for those where we don't have integration yet purpose.

Not a plan but we wrote this up a while back as an exploration into which systems/platforms we can target. We're really hoping the community continues to step up with more plugins and integrations so we can focus on the core service.

Not thinking about you guys needing to write these integrations, but if there's interest on their sides for building it themselves?

Depends on the project, the muOS team is keen to integrate RomM directly in a future release, and the Retrodeck team is willing to partner on support.
