How to use NVRAM on library API

    nes.rom.load('rom/KirbyAdventure.nes')
      .then(nes.start)
      .then(nes.nvram);

This is what I have for the rom loading process I can do everything else but the NVRAM so I can save the game progress and load it up. If you could help that would be great. I already looked at the API.md but there is no clear documentation on how to use the NVRAM

if you need to look at the whole code.
