github.com/emmercm/igir @v5.3.0

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!

What does Igir do?

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)
• 🔢 Create playlists for multi-disc games in mass (see playlist 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)

How do I run Igir?

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:

npx igir@latest [commands..] [options]
