RomM – An open-source, self-hosted ROM manager and player
RomM is a self-hosted app that allows you to manage your retro game files (ROMs) and play them in the browser. Think of it as Plex or Jellyfin for your ROM library: it automatically fetches metadata, artwork, and game information from online metadata sources to transform your folders into a browsable collection. You can play games directly in the browser for consoles like the N64, Game Boy Advance, Nintendo DS, and PlayStation 1, using the integrated web emulator (https://emulatorjs.org/).

In plain words
RomM is a self-hosted app for organizing and playing retro game files in a web browser. It automatically collects metadata, artwork, and game information to create a browsable ROM library similar to Plex or Jellyfin. Users can play games directly in the browser for systems including N64, Game Boy Advance, Nintendo DS, and PlayStation 1 using an integrated web emulator. The project supports integrations with platforms like Playnite, muOS, and Decky Loader, making it accessible across Windows, handheld devices, and Steam Deck.

RomM is a self-hosted app that allows you to manage your retro game files (ROMs) and play them in the browser. Think of it as Plex or Jellyfin for your ROM library: it automatically fetches metadata, artwork, and game information from online metadata sources to transform your folders into a browsable collection. You can play games directly in the browser for consoles like the N64, Game Boy Advance, Nintendo DS, and PlayStation 1, using the integrated web emulator (https://emulatorjs.org/). Members of the community have released integrations for Playnite (Windows), muOS (Anbernic handhelds) and Decky Loader (Steam Deck), with many more in the works. The team has been working on RomM for just over two years now, and we're incredibly proud of what we've built so far. There's no company behind the project, just a bunch of friends building something together that we've wanted for a long time. And of course, the code is open-source and AGPLv3 licensed.

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
