| ==Instructions==
| | '''3ds_hw_test''' is a <code>.firm</code> 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. |

| *[[3DS:luma3DS|Luma3DS]] or [[3DS:fastboot3DS|fastboot3DS]] Custom firmware installed on your console
| |
| *the latest release of [https://github.com/aspargas2/3ds_hw_test/releases/download/v0.1.0-alpha/3ds_hw_test.firm 3ds_hw_test]
