What romlm is

romlm is a free Python command-line utility for organizing retro-game ROM collections on Windows, macOS, and Linux. It extracts .7z and .zip archives into subfolders and can repack uncompressed files in either format while preserving nested folders. Sorting places files in A–Z directories and can separate homebrew, pirate, or user-defined tag folders. Duplicate cleanup examines filename information such as region, beta status, revision, version, and release date to select a candidate to keep. Verbose logging shows the script’s activity. Additional utilities remove system metadata files, including desktop.ini and .DS_Store, and delete empty subdirectories after sorting. The maker says the features are tested on No-Intro ROM sets and should work with similarly named collections. romlm is described for preparing libraries for Analogue Pocket and Emulation Station-based handheld systems. Installation options include pip, a custom Homebrew tap, release binaries, or manual Python installation and script use. The repository uses the MIT License and invites issue reports or pull requests.

Who it suits

romlm suits people maintaining ROM libraries for Analogue Pocket or Emulation Station-based handheld systems. It is for users comfortable running a command-line Python tool.

What it does well

Free on Windows, macOS, and Linux
Extracts and packs .7z and .zip
Sorts by letters and custom tags
Filename-based duplicate cleanup
Verbose activity logging

What to know first

Command-line tool
No metadata scraping
No file renaming
No hash verification

Limits

romlm's duplicate cleanup chooses a candidate from filename details rather than hash verification, and the tool does not scrape metadata. On macOS, supplied binaries are not properly signed and require removal of the quarantine attribute.

Getting started

Open the romlm GitHub repository
Install through pip, the custom Homebrew tap, a release binary, or manual Python setup
Run the command-line tool against your ROM collection
Choose archive extraction or packing for .7z and .zip files
Apply A–Z or tag-based sorting and duplicate cleanup
Remove macOS quarantine attributes when using unsigned macOS binaries

Verdict

romlm focuses on archive handling, folder organization, duplicate selection, and cleanup rather than library metadata. Its free, multi-platform installation options make it practical for command-line ROM maintenance.
