Pronounced "eager," Igir is a zero-setup ROM collection manager that sorts, filters, extracts or archives, patches, and reports on collections of any size on any OS.
See the project website for complete documentation, installation & usage instructions, and examples!
A video of an example use case:
With Igir you can manage a ROM collection of any size:
- 🔍 Scan for DATs, ROMs, and ROM patches—including those in archives (see scanning & archive docs)
- 📂 Organize ROM files by console (see DAT docs)
- 🪄 Name ROM files consistently, including the right extension (see DAT docs)
- ✂️ Filter out duplicate ROMs, or ROMs in languages you don't understand (see filtering docs)
- 🗜️ Extract or archive ROMs in mass (see archive docs)
- 🩹 Patch ROMs automatically in mass (see scanning & patching docs)
- 🎩 Parse ROMs with headers and optionally remove them (see header docs)
↔️ Build & re-build (un-merge, split, or merge) MAME ROM sets (see arcade docs)- 🔮 Report on what ROMs are present or missing for each console and create fixdats for missing ROMs (see reporting & DAT docs)
Either download the latest version for your OS from the releases page, or if you have Node.js installed you can use npx to always run the latest version from the command line:

Example use cases:
Merge new ROMs into an existing ROM collection and delete any unrecognized files:
igir copy clean --dat "*.dat" --input New-ROMs/ --input ROMs/ --output ROMs/
Organize and zip an existing ROM collection:
igir move zip --dat "*.dat" --input ROMs/ --output ROMs/
Generate a report on an existing ROM collection, without copying or moving ROMs (read only):
igir report --dat "*.dat" --input ROMs/
Produce a 1G1R set per console, preferring English ROMs from USA>WORLD>EUR>JPN:
igir copy --dat "*.dat" --input "**/*.zip" --output 1G1R/ --dir-dat-name --single --prefer
-language EN --prefer-region USA,WORLD,EUR,JPN
Copy all Mario, Metroid, and Zelda games to one directory:
igir copy --input ROMs/ --output Nintendo/ --filter-regex "/(Mario|Metroid|Zelda)/i"
Copy all BIOS files into one directory, extracting if necessary:
igir copy extract --dat "*.dat" --input "**/*.zip" --output BIOS/ --only-bios
Create patched copies of ROMs in an existing collection, not overwriting existing files:
igir copy extract --input ROMs/ --patch Patches/ --output ROMs/
Re-build a MAME ROM set for a specific version of MAME:
igir copy zip --dat "MAME 0.258.dat" --input MAME/ --output MAME-0.258/ --merge-roms split
Copy ROMs to an Analogue Pocket and test they were written correctly:
igir copy extract test --dat "*.dat" --input ROMs/ --output /Assets/{pocket}/common/ --dir
