What level of permissions are required in order to write to DSiWare save files? Can such a thing be done on ARM11, particularly without a kernel exploit?

I'm wondering for the prospects of downgrading the NATIVE_FIRM of 11.0.0-33, of course.

I'm going to assume that there's no official way to back up your DSi saves to SD Card - if there was, you could just dump the movable.sed of the latest firmware system (because apparently you can dump latest firmware's NAND now) and use it to properly encrypt the hacked save.

I believe DSi Games, including their saves, are stored on NAND, which is why we need arm9 access currently to install the exploit. This is also the reason the exploit can currently read from and write to NAND.
