Quick update for what's going on behind the scene, mostly for people that are not on the Discord channel...
Arcadeflow 10.0 is shaping up pretty well, this will be a huge update release.
First of all the archive format will change from .tar.gz back to .zip; you'll receive a notification when it's available, but you'll have to manually download and unpack it, just for this version.
The greatest addition will be an internal scraping engine based on screenscraper.fr, this will allow you to get metadata and/or media for your romlists, in a format that's Attract Mode and Arcadeflow friendly. I'm ironing out the many quirks that a process like this can have, so stay tuned for the final release
