mchughalex/skate3recomp — reverse-engineered prompt

I want a native PC build of Skate 3 that works on Windows, Linux, and if possible macOS on Apple Silicon, with Windows treated as the main polished version since that seems the most reliable. Please set it up so the app launches, lets me pick my own legally owned Skate 3 ISO, extracts the needed game files, and then gives me a simple Start Game flow.

Keep the original game files out of the repo and make sure it is clear the user has to provide their own copy. I also want support for DLC if package files are dropped into a dlc folder, plus the experimental true 21:9 ultrawide mode. Controller support should be the default, especially Xbox style input, but keyboard and mouse controls should also be available in settings. The in game settings menu should be reachable with Escape or the controller menu combo.

If there are platform quirks, like Linux sometimes being better through Proton or macOS being experimental, handle that sensibly. Please get it building and runnable from source, and check current docs online if you need to.
