Adding roms

Add ROMs for yourself using localStorage

Navigate to the server public root (e.g. http://localhost:3000), click "+ Add ROM files" and follow the instructions. The ROMs will be saved into your browser cache and other users will not be able to access them.

Add ROMs for all users

Open src/config.js and add a new key under the defined config.ROMS. For example:

myrom: {
  name: "My Rom",
  description: <span>This is my own homebrew NES rom</span>,
  url: "http://localhost:3000/roms/myrom/myrom.nes"
}

If you add your rom file now under public/roms/myrom/myrom.nes, the game should start playing as you navigate to http://localhost:3000/run/myrom
