3ds_hw_test is a .firm application that tests a 3DS console's RAM for errors. There are plans to expand the test so it checks more types of hardware, but so far these plans are entirely a work-in-progress.

Instructions

What You Need

• Either of the following:
  • Luma3DS' boot.firm on the root of the SD card
  • fastboot3DS installed to FIRM partition(s)
• The latest release of 3ds_hw_test (the 3ds_hw_test.firm file)

7. Press any button to start the test
   • The test will take around 30 minutes for an old model and around 45 for a new model
