That switch looks really flimsy -- like it was cut out with a knife. I guess it's more convenient that flashing between DS and ntrboot modes though.
Wish someone would just clone the ak2i with a better fitting shell and update its bootloader for 11.6.
What's wrong with the ak2i? The shell on mine is fine, and one cool think I noticed after installing ntrboothax on it, is that the card logo is the original ak2i one and it actually runs fine on my n3ds now. Something it didn't do before which is why I had retired it. So glad it's working again now. (does it not work on latest firm on o3ds?)
