Release Highlights

The theme of this release is: more standard, less surprising behavior.

Semi-breaking fix: standard 1G1R handling

1G1R preferences are now applied against DATs, no matter what input files you have.

Previously, Igir took more of a "best available" approach that didn't match the behavior of other ROM managers. As an example, let's say a game has USA, Europe, and Japan clones. Previously, if you preferred USA but only had the Japan clone in your input, the Japan clone would be selected because it was the best available. No other ROM manager behaved like this, all of them would have ignored the Japan clone because the USA clone is what is preferred.

Thank you @IDmedia and @ozboss for the discussion on this!

Semi-breaking fix: don't manipulate DAT names

Igir was stripping some common prefixes and suffixes from DAT names to make for cleaner folder names with --dat-name, but no other ROM manager behaves this way. This processing has been removed, which may change your output directory paths. Thank you @kriswilk for the report!

Feature: support for No-Intro "standard" DATs

No-Intro's "standard" DATs use, ironically, non-standard XML attributes for parent/clone information. These are now handled correctly. Thank you @R1nlz3r for the report!

Feature/fix: filter updates

• --filter-category-regex <pattern> option added for DATs that supply category info. Thank you @steven-sheehy for the suggestion!
• Languages in game names are now preferred over the release region's language. Thank you, @ozboss for the report!
• SNES enhancement chip ROMs are now considered "non-retail". Thank you @baglio for the suggestion!
• MAME bootlegs and hacks are now considered "non-retail".
• Redump revision tags without numbers are handled better.
