ClrMamePro vs RomM

ClrMamePro scans and rebuilds MAME machine sets, checking ROM, sample, and CHD files for missing, unnecessary, or incorrectly named files. Its Rebuilder matches input files against a database using hashes and size, then writes correctly named machine files to an output folder. The package includes a graphical interface and a command-line executable with Scanner, Rebuilder, and Dir2Dat functions. The tools can use a MAME executable's listxml or listsoftware export as a data source. They use 7z.dll for 7z archive support and can produce zip, 7z, or decompressed output. A suitable DatFile allows use with systems beyond MAME. There is no install wizard; users unpack the archive into a folder. Current builds run on Windows 7 and higher, while older documentation describes Linux use under WINE or similar. The software is freeware, and the copyright notice identifies Roman Scherzer as its author; he says he started clrmame(pro) in 1997. Incorrect settings or removal operations can cause data loss, so the author recommends backups.

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.
