Nucleus Coop Support

[Jeremy]

Please add support for Nucleus Coop. It is technically an emulator (it uses the Goldberg Emulator mostly). Nucleus Coop has over 10,000 users and is growing. It allows programs to become split-screen that do not natively support split-screen. Nucleus Coop is open source: https://github.com/ZeroFox5866/nucleuscoop/releases. If needed, you can create a pull request to edit the code or take the code and edit it to make a 3rd party plugin.
