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 tools 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).
