Audit Tool: Add Region Prioritization for Duplicate Filtering

📋 Summary

Enhance the Audit Tool with the ability to prioritize regions when identifying duplicate games. This would help users more effectively manage large ROM sets by automatically surfacing lower-priority versions for review or cleanup—supporting workflows like “One Game One ROM.”

🎯 Key Feature

Add a customizable region priority system to the Audit Tool that evaluates duplicates based on the user’s preferred order of regions.

🧪 How It Works

• Users define their region priority (e.g. 1. North America, 2. Europe, 3. Japan).

• When the audit identifies multiple ROMs of the same game:

  • The version from the highest-priority region is kept.

  • All others are marked as duplicates.

• This enables smart filtering and cleanup without relying solely on file names or manual inspection.

📦 Benefits

• Helps reduce clutter from multi-region sets.

• Streamlines curation for users targeting minimal sets.

• Saves space and simplifies library management.

• Lays groundwork for similar prioritization systems (e.g. version, language) later on.
