~~==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.

~~===What you need===~~

*[[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]~~

=== Hardware ~~test~~ ===

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.

== Instructions ==

=== What You Need ===

* [[3DS:boot9strap|boot9strap]], [[3DS:GodMode9|GodMode9]] or [[3DS:fastboot3DS|fastboot3DS]] installed to FIRM partition(s), or a [[3ds-guide:ntrboot.html|ntrboot]] compatible flashcart

* [[3DS:Luma3DS|Luma3DS]]' <code>boot.firm</code> on the root of your SD card

* The latest release of {{GitHub|aspargas2/3ds_hw_test/releases|3ds_hw_test}} (the <code>3ds_hw_test.firm</code> file)
