arthurvictorrodrigues38-create/Sm64coopdxapkrepackged ? reverse-engineered prompt

Help me turn this repository into a clean, easy to understand home for my SM64CoopDX mod pack.

I want the README rewritten so regular people can quickly see what this is, how to download it, how to install it on Android, and how to try it on Windows with Winlator. Please make it clear that this is a mod pack, not the original game, and keep the note that people should buy the game and not pirate it.

Also make the repo feel more complete by organizing the mod list, adding simple instructions for testing, and telling users what to do if they find bugs or device compatibility problems. If you need current setup details or best practices, look them up online first.

Please keep the tone friendly, simple, and beginner friendly, and make sure the page looks good for someone opening the GitHub repo for the first time.
