Emu-Elec Game Indexer

Standalone Python app that scans a drive for game image files and updates the gamelist.xml file so Emu-Elec can detect all games installed.

Simply run the app, select your drive, you can then update per folder or batch update the whole drive.

When complete, it will return how many were added / removed to that folders gamelist.xml

What it does

Scan Drive	Walks the chosen drive and lists every folder that contains a `gamelist.xml`
Update (per row)	Backs up to `gamelist-backup.xml`, then syncs the XML with the actual ROM files in that folder
Update All	Runs Update on every found folder, one at a time, in order

Sync rules:

Entry in XML but file missing on disk → entry is removed
File on disk but not in XML → a minimal entry (<path> + <name>) is added
Entries whose <path> points into a subfolder (e.g. ./downloaded_images/…) are left untouched
Only direct files with known ROM/archive extensions are considered (.zip, .7z, .nes, .gba, .iso, .chd, etc.)

The status bar and progress bar update in real time as each folder is processed.
