elripalda/RecompLauncher ? reverse-engineered prompt

Build me a Windows app that acts as a single launcher for PC recomps, so I can discover them, install them, update them, and launch them from one place.

I want it to show a catalog of games with screenshots, what each one needs, and how well it runs for other players. Each game should have its own page, support multiple versions if they exist, and let me switch versions or keep a few installed side by side. It should handle one click install and updates from the developer’s GitHub release, verify downloads with checksums, and let me point it at my own disc image or game folder when setup is needed.

Please also add save backups before updates, cloud saves for signed in users, a full screen Big Picture mode for controller use, and per game visual effects like CRT filters. I’d like a way to see player reports, follow verified developers, and get notified when they release something new. If you need current docs or API details, look them up online.
