BMBT3DS is a bare metal button testing .firm payload for the Nintendo 3DS. It can be used to test all buttons on the console, and to see if one is being held down or not.

Instructions

What you will need

• boot9strap, GodMode9 or fastboot3DS installed to the FIRM partition(s)
• Luma3DS' boot.firm on the root of your SD card
• The latest release of bmbt3DS (the bmbt3ds.firm file)

Section I - Preparing

1. Power off your console
2. Remove the SD card from your console and insert it into your computer
3. Copy bmbt3ds.firm to the root of your SD card
4. Rename boot.firm to luma.firm
5. Rename bmbt3ds.firm to boot.firm
6. Safely eject the SD card from your computer and reinsert it into your console

Section II - Running the test

1. Power on the console without pressing any buttons

This payload does not show anything on either screens until a button is pressed. Refer to the attached image for what parts of the screen will light up for each button pressed.

1. Press each button once, verifying that the corresponding button shows up on the top screen. If it does not show up, the button pressed may be faulty. If you see a constant white square for one button and you are _not_ holding the button down, that button may be stuck and could be the source of some issues.
2. Once you are finished with the button tester, press the power button once to power off the console
3. Remove the SD card from your console and insert it into your computer
4. Delete boot.firm from the root of your SD card
5. Rename luma.firm to boot.firm
6. Safely eject the SD card from your computer and reinsert it into your console
7. Power on your console

If all went well, you have successfully tested the buttons on your console.
