JRomManager vs RomM

JRomManager is a free Java ROM manager for organizing and checking ROM collections. It works with MAME and Logiqx DAT files and can also import data from the MAME executable. Its tools scan, fix, and rebuild split, non-merged, or merged sets. It supports ZIP and 7z archives, TorrentZip, RAR4 and RAR5 decompression, and multi-volume RAR and 7z decompression. Checks include full or on-demand SHA1 scans, MD5 for older DAT files, CHD, and Software Lists. One important CHD limit: verification reads the header for MD5 or SHA1 but does not hash the CHD data. With MAME linked to a profile, its viewer can launch games or software marked available. Batch tools include a directory updater, torrent checker, and archive compressor. Desktop packages are listed for Windows x64, macOS x64 and ARM, and Linux x64; it can also run on an OS with Java 21. Server mode serves a web interface. Simple Server lacks encryption, access control, and DDoS protection; Full Server offers accounts, access rights, and TLS 1.3, but is experimental.

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.
