Release Highlights

This release addresses several bugs reported by the community. As a reminder, you too can report bugs by opening a new GitHub issue! Detailed bug reports help make Igir more stable for everyone.

Fix: copying .zip archives with excess file entries

Igir has an optimization that if a zip file in the input directory is already correct, it will just copy the file as-is to the output. There was a bug where input .zip files with excess file entries were being copied even though --allow-excess-sets wasn't being provided. This has been fixed.

Fix: not requiring MAME CHD disks to be in the ROM zip

MAME expects CHD disks to be uncompressed and in a location relative to the ROMs. There was a bug where Igir was preferring that CHD disks be in ROM zips, but they shouldn't ever be. Thank you @​dariaambrose for the report!

Fix: legal POSIX filename characters

Igir was replacing filename characters that are illegal for Windows but legal for POSIX regardless of the OS. POSIX systems now preserve almost all filename characters. Thank you @​pasnox for the report!

Fix: TorrentZip filename sorting validation

v5.3.0 introduced a bug where filenames within TorrentZip archives were not being validated correctly, telling users that some written files were invalid even though they weren't. Thank you @​synthic for the report!

Fix: CRC32 padding for .gz and .rar archives

CRC32 checksums read from .gz trailers and .rar headers were not being zero-padded to the correct string length, preventing some file entries from being matched correctly and giving false-positive errors during testing. Thank you @​quicksteps529 for the report and @​yhay81 for the diagnosis!

Release Highlights

Feature: RVZ, GCZ, and WIA extraction without dolphin-tool

Up until this release, Igir had been relying on the dolphin-tool tool from the Dolphin team for extracting multiple compressed GameCube and Wii files (as most ROM managers do). This requires ROM managers to extract these compressed files to temporary files when deep scanning, increasing the time required and wear & tear on the hard drive. And depending on how the version of dolphin-tool was compiled, it may require installing other libraries to work, making installation & usage complicated.

Igir can now read and extract RVZ, GCZ, and WIA files natively, without the need for dolphin-tool or temporary files. Users should see substantial speedups when scanning or extracting these files. This update has the added benefit that Igir can now show meaningful progress bars when processing CHD files.

Fix: filename extension correction disabled by default for dir2dat

@​sebbiecoe found some undesirable behavior where Igir was correcting (including stripping) filename extensions when using the dir2dat command. This behavior doesn't make sense because it only makes sense to generate dir2dat files from input files whose structure and naming you trust. The default --fix-extension auto mode will now skip extension correction when dir2dats are being generated. You can enable the old behavior by providing the --fix-extension always option.

I welcome everyone to keep submitting issues when you think Igir has default behavior that doesn't make sense or is surprising. Igir has an overall goal to have defaults that make the most sense for the largest number of people.

Release Highlights

Feature: CHD extraction without chdman

Up until this release, Igir had been relying on the chdman tool from the MAME team for extracting CHD files (as most ROM managers do). This requires ROM managers to extract CHDs to temporary files when deep scanning, increasing the time required and wear & tear on the hard drive. And depending on how the version of chdman was compiled, it may require installing other libraries to work, making installation & usage complicated.

Igir can now read and extract all versions (v1-5) of CHD files natively, without the need for chdman or temporary files. Users should see substantial speedups when scanning or extracting all CHD files. This update has the added benefit that Igir can now show meaningful progress bars when processing CHD files.

Fix: correcting the extension of extensionless files

@​dariaambrose found a bug where Igir would mangle filenames when Igir tried to correct the extension of files without an extension. This has been fixed. This primarily affected a subset of CHD files.

Feature: console output token updates

@​jim-edwards reported two items that have both been addressed:

• Atari Jaguar CD was not being matched correctly, ROMs were being sorted into the Philips CD-i directory.
• Support for the VM Labs Nuon has been added (though only RomM recognizes it right now).

Release Highlights

This release brings a handful of bug fixes based on reports from community members. Thank you!

Fix: zero-byte files in zip archives

@​Ooopz found a bug with copying or moving zip archives without extracting or re-zipping them. When the zip contained a zero-byte file (common with Nintendo DSi), Igir wouldn't match it correctly. This has been fixed.

Fix: large multi-file TorrentZip archives

@​cmcginty found a bug with how Igir was creating TorrentZip archives with multiple files whose uncompressed size totalled >3.99GiB. This has been fixed.

TorrentZip files written with old versions of Igir are still valid zip files that Igir can read; they just aren't valid TorrentZip files. Their raw-file checksums would not have matched those of TorrentZip files produced by other ROM managers. Igir will overwrite old, invalid TorrentZip files if you provide the --overwrite-invalid option. RVZSTD files were not affected.

Fix: don't quick-scan checksums when testing files

When testing files because of the test command or the --overwrite-invalid option, checksums for files within archives in the output directory are now always calculated from their decompressed bytes. Previously, Igir might have trusted the checksums in the archive's file headers.

Fix: disc-merging GD-ROM CHDs

There was an issue where multi-disc Dreamcast GD-ROMs would duplicate the CHD for every track file if the --merge-discs option was used. This has been fixed.

v5.2.0

Release Highlights

Optimization: built-in Node.js zlib library

CRC32 checksum calculation and Zstd decompression of zip archives now use Node.js' built-in zlib library. Node.js v24+ (and Bun v1.3.13+) use zlib-ng, which can take advantage of SIMD acceleration when possible for your CPU. That is to say, you should see a measurable speed improvement, and it is likely to improve over time.

The built-in Zstd support did require dropping support for Node.js v20, which reached the end of security update support on April 30th, 2026.

Fix: CD-ROM CHDs with disc merging

There was a bug with the --merge-discs option where CD-ROM CHDs were deemed "incomplete" and would not have been written to the output directory. This would have also incorrectly cleaned existing CD-ROM CHDs in the output directory. This has been fixed.

Release Highlights

Feature: install on Windows via Scoop

Support for installing Igir on Windows via Scoop has been added. Scoop is a lot like Homebrew on macOS and Linux, and many applications, such as Bun and Deno, officially support it.

The Windows binary is also now compiled with an Igir logo, replacing the default Bun logo.

Refactor: non-overlapping dir letter ranges

An oversight has been fixed when using the --dir-letter --dir-letter-limit <limit> --dir-letter-group options together. Previously, letter ranges could overlap, producing subdirectories such as:

ROMs-Output/A-D/...
ROMs-Output/D-G/...
ROMs-Output/G-J/...

Now, letter ranges will not overlap, producing subdirectories such as:

ROMs-Output/A-C/...
ROMs-Output/D-F/...
ROMs-Output/G-J/...

Thank you @​JosVerheij for the feedback!

Fix: double nesting merged disc subdirectories

A bug has been fixed where disc-based games would be nested under subdirectories based on the game name twice, once because of --merge-discs, and once because of --dir-game-subdir multiple/--dir-game-subdir always.

Thank you, @​kevin2845, for the bug report, and @​cookesan, for helping to debug!

Igir, and other open-source projects like it, are a labor of love. They wouldn't be nearly as meaningful without the community supporting them. Constructive feedback and general positivity will always be welcome. Be kind to others, and be kind to yourselves.

Release Highlights

Feature: option to re-pad trimmed ROMs

A new --trim-add-padding option has been added to allow you to pad trimmed ROMs such that they match the size & checksums found in a matching DAT.

Feature: providing multiple patterns to regex options

--dat-name-regex <pattern>, --dat-name-regex-exclude <pattern>, --dat-description-regex <pattern>, --dat-description-regex-exclude <pattern>, --filter-regex <pattern>, --filter-regex-exclude <pattern>, --filter-category-regex <pattern>, --prefer-game-regex <pattern>, --prefer-rom-regex <pattern>, and --prefer-filename-regex <pattern> have all been updated to allow the option to be provided multiple times. When each option is provided multiple times, values will be used in an "or"/"any" fashion.

For example, --dat-name-regex "/Nintendo/i" --dat-name-regex "/Sega/i" now means "match any DAT whose name contains 'Nintendo' (case-insensitive) or 'Sega' (case-insensitive)."

Fix: MAME CHD disk naming & sorting

Two major fixes have been made for handling MAME DATs:

• CHD disks will always have the .chd extension added. MAME requires this, but confusingly doesn't include it in the disk name in the DAT.
• When zipping ROMs, CHD disks will always be put in a subdirectory using the machine's name (as if --dir-game-subdir always was provided, but only for CHD disks). MAME requires this sorting (and it helps deconflict files of the same name).

Thank you @​cinnamonmatexfce for the bug report!

Fix: update to RVZSTD to match RomVault.

RomVault v3.7.6 changed how zero-byte/empty files are compressed in RVZSTD archives, and Igir has been updated to match. RVZSTD archives containing zero-byte files that were written by older versions of Igir (or RomVault) will have to be rewritten.
