    It's possible?

    I guess it's possible because the JKSM runs on the latest version.

    I've successfully backed up my friend's save on LoZ AtBW and Smash using menuhax and JKSM before using the DSiWare Downgrade.

    You need a privileged exploit to write to dsiware game saves. They're inside the nand.

    Then there is not possibility to downgrade via software without another console.

    JKSM only uses an arm11 userland exploit. Dsiware titles are stored on the nand, so you would need a kernel exploit to read and write to the saves. The only thing that I can think of that would allow you to read or write to the saves without a kernel exploit is if you transfer the DsiWare game to your SD card and someone figures out how to access the saves from there, but that would probably be a lot more complicated. I'm pretty sure you need an arm9 kernel exploit to write to DsiWare saves, but there would be no point in downgrading if there was one.

    What if I fill the nand with DSiWare games?

    They are leftover go to the sdcard?

    You still can't play DsiWare games off of the SD card. When you transfer a DsiWare game to the SD card, the save also transfers with it, so someone could figure out a way to change the save then write it back to the system, but that might not be possible. It would be better to just wait for an arm9 kernel exploit.

    I remember that there was such a tool required a long time ago to install the original sudokohax (because you use some sort of dev DS save injector... I think the same tool could extract saves too. If fieldhax can run the dgTool.nds required for the firm downgrade... It can technically run this tool too)

    @Apache Thunder would know a lot on this because I believe he wrote the original sudokohax guide

    I can try to test this out later if I ever get the chance

    Did the tool require a kernel exploit to use? Or could it inject a save into a DsiWare game stored on the SD card?

    it required sudokohax.... Which can boot into boot.nds. And since feildhax can boot into boot.nds too... Cause TWL firm technically has a little more authority (which is why we can downgrade firm).... That is all we need for it to work

    Does sudokuhax work on 11.0?

    Technically it should since Fieldhax works

    The way fieldhax works is you need another 3ds with custom firmware to install the save, then you do a system transfer to transfer the save to the normal 3ds, so I don't think that method would work for injecting a save without a second 3ds because it requires an arm9 exploit. I'm still wondering if you'd be able to inject a save to a Dsiware game that's stored on the SD card though, because that might be possible but no one has tried it yet
