Release Highlights

This release addresses some user-submitted bugs & feature requests.

Feature: --patch-only option

The option lets you write only patched ROMs, skipping all others.

Thank you @noah978 for the suggestion!

Feature: --trim-scan-files <mode> option

The option lets you always or never scan files not inside archives. --trim-scan-files never can help speed up your processing time if you know you definitely don't have any trimmed ROMs.

Thank you @HeroponRikiBestest for the suggestion!

Feature: handle region variants for {emulationstation} and {romm}

Some ROM frontends differentiate regional variants of consoles, such as:

• NEC PC Engine vs. TurboGrafx
• Nintendo NES vs. Famicom
• Sega Genesis vs. Mega Drive

Igir will do its best to pick the right one based on DAT information.

Thank you @dirn and @Europia79 for working through this with me!
