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!
With Igir you can manage a ROM collection of any size:
- 🔍 Scan for DATs, ROMs, and ROM patches—including those in archives (see [scanning](https://igir.io/input/file-scanning) & [archive docs](https://igir.io/input/reading-archives))
- 📂 Organize ROM files by console (see [DAT docs](https://igir.io/dats/overview))
- 🪄 Name ROM files consistently, including the right extension (see [DAT docs](https://igir.io/dats/overview))
- ✂️ Filter out duplicate ROMs, or ROMs in languages you don't understand (see [filtering docs](https://igir.io/roms/filtering-preferences))
- 🗜️ Extract or archive ROMs in mass (see [archive docs](https://igir.io/output/writing-archives))
- 🔢 Create playlists for multi-disc games in mass (see [playlist docs](https://igir.io/output/playlists))
- 🩹 Patch ROMs automatically in mass (see [scanning](https://igir.io/input/file-scanning) & [patching docs](https://igir.io/roms/patching))
- 🎩 Parse ROMs with headers and optionally remove them (see [header docs](https://igir.io/roms/headers))
- ↔️ Build & re-build (un-merge, split, or merge) MAME ROM sets (see [arcade docs](https://igir.io/usage/arcade))
- 🔮 Report on what ROMs are present or missing for each console and create fixdats for missing ROMs (see [reporting](https://igir.io/output/reporting) & [DAT docs](https://igir.io/dats/overview))
## How do I run Igir?
Either download the latest version for your OS from the [releases page](https://github.com/emmercm/igir/releases/latest), or if you have Node.js installed you can use [`npx`](https://docs.npmjs.com/cli/v9/commands/npx) to always run the latest version from the command line:
```shell
npx igir@latest [commands..] [options]
```
