Acer C720 Chromebook gaming N64
A demonstration video showing the capability of playing N64 games on the Acer C720 Chromebook.
This is a different operating system known as Ubuntu, running on top of ChromeOS. It's launched from what's called "Crouton". You cannot run these emulators on ChromeOS.
Note: The best N64 emulator is Mupen64Plus, you can install it from the terminal "sudo apt-get install mupen64plus"
Then you'll want to Google "M64py" and install the frontend. Mupen64plus normally doesn't have a user interface/frontend so this is the solution.
