-==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 ===
+== Instructions ==
+=== What You Need ===
+* Either of the following:
+** [[3DS:Luma3DS|Luma3DS]]' <code>boot.firm</code> on the root of the SD card
+** [[3DS:fastboot3DS|fastboot3DS]] installed to FIRM partition(s)
+* The latest release of {{GitHub|aspargas2/3ds_hw_test|3ds_hw_test}} (the <code>3ds_hw_test.firm</code> file)

-#Turn on your 3DS
+# Reinsert the SD card into your console
-#Press any button to start the test
+# Power on the console without pressing any other buttons
-#The test will take up to 45 minutes, when it's done press any button to turn it off, then open the newly generated <code>HWTEST.LOG</code> file on the SD card in a text editor
+# Press any button to start the test
-#Scroll down to the end, and look at the number of errors
+#* The test will take around 30 minutes for an old model and around 45 for a new model
-#*If the number is 0 your console's RAM is not the issue
+#** If you are unsure what model the console is, look at the shoulder buttons - a new model has four ({{Key press|L|ZL|ZR|R}}), and an old model has two ({{Key press|L|R}}
-#*If the number is more than 0, your console's RAM is dying and you need to replace the motherboard
+# When the test finishes, press any button to turn the console off and insert your SD into your computer
-#Delete <code>boot.firm</code> and rename <code>luma.firm</code> to <code>boot.firm</code>
+# Open the newly generated <code>sd:/HWTEST.LOG</code> file in a text editor, then scroll to the end and look at the line that says <code>[ARM11] Done. ___ total errors detected.</code>
+#* If the number on this line is 0, your console's RAM is not the issue
+#* If the number on this line is not 0, your console's RAM is dying and you need to either repair or replace the motherboard
