DS Diag is a Nintendo DS diagnostic 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.

Changes:

*Added DSLite brightness control.
+Fixed the IP bug.
+Changed Backlight Control to L and R
