Here's my new app for the Nintendo DS (yes, just mine). It's very boring recovering from surgery, so I decided to make some use of my time and make this. It's a DS diagnostics tool. It will test to see if FAT and SRAM are working. As well as making sure the backlights work. It will also retreieve your DS's IP at the touch of a button but this is currently incorrect. It is very simple an doesn't have a ton of features but I will be adding more including a nice GUI, as time permits.
Remember to patch it with DLDI!
Controls:
X:Turns the top screen's backlight on.
Y: Turns the top screen's backlight off.
L: Turns the bottom screen's backlight on.
R: Turns the bottom screen's backlight off.
START: Gets your DS's IP (Currently broken and displays what appears to be random numbers).
Enjoy!
PS: If your card can't pass this, you should buy a new card.
