[Utility] RomSieve: Cross-platform 1G1R curation and .m3u generator

[MadVintager]

Hey everyone,

I built RomSieve to make curating ROM sets before importing them into LaunchBox less of a chore. Instead of messing with old Win32 clr tools or batch scripts, it gives you a clean desktop app to filter sets down to what you actually want to play.

It handles deterministic 1G1R filtering based on your region and language priorities, strips out bad dumps, and automatically generates .m3u playlists for multi-disc games (PS1, Saturn, etc.) so LaunchBox doesn't end up with duplicate entries for every disc. It also parses TOSEC naming directly from filenames on top of standard DAT-based sets like No-Intro, Redump, and MAME. Everything has a full dry-run mode so you can preview changes before touching your disk.

On the roadmap, I'm working on multi-DAT processing in a single pass, on-the-fly ROM patching (translation, bugfixes) prior to filtering, and several other workflow features.
