Moments after submitting a new run for the first time in quite a while, I noticed that a new build of Retroarch has appeared in the resources section. I've downloaded this new, what Im assuming is a "custom build" of the ui and notifications to the new 2019 rule set.

Does this mean the run I just submitted is invalid? Even with the window of my retroarch being shown at the end of the clip?

As far as I see, the run is completely valid following the current emulation rules, so there's no need to worry about that :D That resource was added just for the sake of keeping things updated, since some people are already using this emulator and it's known to be more precise than Fusion or another ones.

More updates to the rules will come in the future following the 2019 rule set.

Affirmative, thanks for clearing that one up.

I'm going to take the liberty of adding that frame counter to the bottom of my future runs just to make sure to stay in compliance. Also, I don't know how obfuscated the kiosk mode password is in the retroarch.cfg files, but perhaps disabling the features that invalidate runs (Rewinding, Save States) and hard locking that FPS display up and enabling the Kiosk password to something shared with the moderation team could maybe help keep things standardized for runs on Retroarch.

Not entirely sure if it could be useful, just a thought.
