Homebrew Permissions required to write to DSiWare saves

[Myria]

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.

Iirc it needs an arm9 exploit.

It would appear pxi:am9 is needed, so you likely need a11 kernel to get it.

y8 probably has this figured out by now but can't disclose it because you know why

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.
