    • Use a FTP client connect to your N3DS.

Tinkering Settings

Edited from BootNTR wiki:

  • Priority (Defaults to TOP) - Controls which screen has the priority to be transferred.
  • Priority Factor (Defaults to 5) - Controls the priority promoted screen's frame-rate factor. When it is set to 1, the top screen have same frame-rate with bottom. When set to 0, only the screen set by priorityMode will be displayed.
  • Quality (Defaults to 90) - Controls the JPEG compression quality (Ranged from 1 to 100; from 1 being lowest quality to 100 for highest quality).
  • Quality of Service Value (Defaults to 20.0) - Limits the bandwidth to work on different wireless environments, the actual bandwidth cost could be lower than this value. Set to 25, 30 or higher on good wireless environment, set to 15 if the WiFi quality is not so good. Setting the value higher than 100 will disable the feature.


  • You will need to activate Memeory Patch for games that use a lot of memory, like OOT3D, Pokémon Games, Mario Games, etc.
  • To stream audio, connect a male to male auxiliary cable from your N3DS to your PC.
