RomM vs ROMSorter

RomM is a free, self-hosted app for scanning, enriching, browsing, and playing a ROM collection. The project says it supports more than 400 platforms, including multi-disk games, DLCs, mods, hacks, and manuals. Compatible games can run in a browser through EmulatorJS and Ruffle without setup, while saves and states sync across devices with conflict resolution. Metadata providers include IGDB, ScreenScraper, LaunchBox, and MobyGames; RomM can also fetch artwork from SteamGridDB and track RetroAchievements. A built-in patcher applies ROM hacks and translations. The project lists granular per-user permissions, OIDC single sign-on, a REST API, and exports for ES-DE and Pegasus. Official clients include a Windows Playnite plugin, the Android Argosy handheld launcher, and the Linux Grout handheld client. A native iOS app is a community project, and the team says it does not regularly review community project source code. RomM is AGPL-3.0 licensed, with no tracking or paid features. Setup help and community discussion are available through Discord.

ROMSorter detects and renames ROMs and other games, with tools for archives, duplicates and file checks. It can zip files, convert supported archive formats by extracting and recompressing them, or unpack archives into a folder. Identical files can be moved into a subfolder named after the original file. A catalog stores file names and hashes for later checks that files have not changed. The program can create DAT files for other ROM manager apps and rename single-file games using a supplied DAT file. It converts BIN/CUE or ISO files to CHD and can extract CHD back to BIN/CUE using chdman. Other tools include building one-game, one-ROM sets from Parent/Clone DAT files with region priorities, sorting Everdrive folders by starting letter, generating M3U playlists, and batch IPS/BPS patching. The current ROMSorter release is for Win-x64 only; its Librarian command-line companion is available across platforms. Both require .NET 6. Linux and Mac Librarian users need an appropriate MAME chdman build for CHD commands. It is free, MIT licensed and provided without warranty.
