Well, you’d need to find a crack separate from a repack because they aren’t in a format that lets you grab the data you need.
Also worth considering that your crack needs to match the game version in most cases. Updates to binary files are likely to make older crack versions incompatible. I tend to just download the repack and add the repack exe to Steam to make everything integrate well and to avoid automatic updates breaking the game.
This sounds about right. They use PlayReady DRM so a browser extension might be able to pull the decryption key during playback. One could download that same stream from that playback season then use ffmpeg with the pulled key to decrypt.
Theoretically. I’d have to do more tinkering than I’m willing to try right now. WideVine is so much easier - just pull some keys from Android.
The best solution might just be to use a VPN like Mullvad, set torrent software like qBittorrent to only use the Mullvad network interface in advanced settings for safety, and grab the video from something like 1337x in a decrypted format.
