Glad to see a new exploit is coming to the DSi, never got either Sudokuhax or 4swordhax but have all the stuff that was already installed still there.
I'd like to ask a bit of an unrelated question though: reading the posts on the 2nd page here about fwtool, would one be able to dump the NAND and CID using that to then be able to decrypt the NAND and downgrade the whitelist without needing a hard mod or other tools (I can do the hard mod part but I can't buy a Raspberry Pi or find a copy of the game required to dump the CID)?
