Hi, I've ordered some cards from Digitopz, which normally are pre-flashed to the latest firmware (1.8.7). I've tested them on my 3DS (which has the latest firmware) and they all seem to work. But when I've tested them on the DSi (don't know which firmware it was), they all did not work. How is it possible? Shouldn't it work on a DSi too when it works on a 3DS.
