DSTWO Firmware Flashing Demonstration
So apart from having absolutely no idea what to do nor if I even did anything, this is supposedly how the DSTWO should be updated on a DS, though for all intensive purposes, I have no clue if it actually did anything.
edit
This demonstration will show no effect on my DSlite as it is for DSTWO flashcarts that do not have their firmware flashed already. For those that need to flash their DSTWO with the latest firmware, read the second paragraph of the annotation.
Added an annotation and changed the title to what it should have been.
The video for updating the firmware on a DSTWO is available here:
