JRomManager vs ROMie

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.

ROMie imports and organizes ROM collections, then copies them to handheld SD cards using the folder layout for a selected device profile. It can create tagged game playlists, normalize filenames into game titles and compare ROM MD5 hashes with the RetroAchievements database to show progress for verified games. Device profiles listed include OnionOS, Knulli, muOS, ROCKNIX and custom profiles. ZIP and 7z archives are accepted when each contains exactly one supported ROM file; they remain compressed in the library and are copied to the device that way. Supported systems include Nintendo, Sega, Atari, Neo Geo Pocket and MAME arcade systems. PlayStation is temporarily unsupported because of multi-disc game complexity. ROMie is free software under the MIT license, with no paid plans stated. Downloads are listed for macOS, Windows and Linux, including Linux x64 and ARM64 builds. The releases page lists v0.9.0-rc.2 as a prerelease.
