build an oversee analysis system from the main emulator to report, stop forum.

Too many different things that don't necessarily relate in the same thread.

If something regressed open a regression report.
Unity games not working with PPU LLVM is a reported issue and it doesn't prevent the games from being playable even in latest build.
Games that need Debug Tab settings don't qualify for the playable status.
Requiring settings is normal, if we made everything accurate by default with zero settings then games would generally run like shit. If you see missing settings for your game, you can add them to the wiki.

New GitHub accounts can't interact with the repository, that's basic anti-spam protection. Wait for the cool down period before it allows you to interact. Otherwise demand better anti-spam measures from GitHub itself, otherwise this is all we can enable. Your so called obsolete forums and wiki allow to properly handle this, by the way.

Of course you can't submit compatibility reports from inside the emulator, like every other emulator, we have better things to waste our time than to reinvent the wheel.

What threads are you talking about that are in the game report section since last year but haven't been added to the compatibility list? There are none. These subforums are automatically scanned for changes.

Most of the rest doesn't make much sense. No one is going to stop working on the things they want to work on to develop some kind of automatic analysis system that you want. If you want to add CD with automated tests to improve stability, be the change you want to make, otherwise no one will do it for you.

Regressions are normal with the amount of modifications on core parts of the emulator that we have on a monthly basis, specially considering the scope of the software, most of them are handled quite fast by the developers that broke it, that's one of the topics I push for the most internally.

Couldn't care less about the piracy arguments, the no piracy rule is not open for discussion.

Telemetry to automatically send data enabled by default will never be added and we also do not want to add any at all even if it's disabled by default at this point in time.

If said steam deck user doesn't want to bother opening the forums or wiki to add their findings for a certain game, maybe they shouldn't be contributing in the first place.

Maybe one could argue forums are not as popular as they once were, and even then I disagree that they're obsolete, as Reddit is essentially a forum based social media and is highly popular, except there you don't control your own forum's data, plus the UX is generally better specially for mobile platforms.
Arguing that wikis are obsolete is just insanity, however.
