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.

The test will take roughly 30 minutes on the Original 3DS, 3DS XL and 2DS, and roughly 45 minutes on the New 3DS, New 3DS XL and New 2DS XL.
