Neo Launcher, available in the IzzyOnDroid F-Droid Repo, has been my solid go-to for replacing Nova.

I prefer a ton of icons/folders/widgets on my home screen, and it supports that dense layout.

I think the local copy I have (on a literal old samsung S3) is the same as what is downloaded from here, with the game cache files: https://sbenny.com/games/puzzle-quest-2.html

I was NOT able to make that work on my current OnePlus, even with the cache files. It fails a validation check on launch.

I would greatly appreciate that

I have never seen those questions answered because it’s a secret sauce that the streaming platforms would patch immediately if it were published. In general though, my understanding is it’s older versions of apk’s on rooted android devices with exploits that allow for harvesting the actual cached files, or in some cases the apk is deconstructed to get access to the API keys so that the files are downloaded directly, though that’s risky as it gets easier to detect a single key doing a giant pull of files faster than someone could reasonably watch the shows.
