This very simple homebrew just flips the number in emummc/emummc.ini that determines if Atmosphere should load emuMMC.


Removes the need for SD pulls to reboot from emuMMC to sysMMC or vice versa if using fusee-primary.


Open the .nro using the HBL.

  • Press - to toggle emuMMC on or off.
  • Press + to exit the application.

Don't attempt to toggle emuMMC if it says something is wrong. That's bad behavior.


  • Install devKitPro
  • Clone recursively
  • Run make
  • ???
  • Profit


  • Dax for recommending simpleini library.
