cemu-project/cemu — reverse-engineered prompt

Build me an open source desktop app like Cemu, a Wii U emulator for 64 bit Windows, Linux, and macOS.

I want someone to be able to install it or unzip it, open the app, choose their Wii U game or homebrew files, and have compatible titles run in a playable way. Keep the first version focused on correctness, stability, and performance, not flashy extras. Include a simple interface for starting games, changing basic emulator settings, and showing helpful errors when something doesn’t work.

Please make the code clean and maintainable, with clear build instructions for each platform and a straightforward release setup. Don’t include any copyrighted games or system files. If you need details about emulator behavior or platform setup, look up current docs online and make sensible choices.
