So, all this talk of Nitrohax being released for 3DS and enabling you to finally use DS Action Replay codes on 3DS reminded me that my old DS Wi-Fi Connection information was destroyed when my O3DS got shorted a while back from a bad repair job on Nintendo's part. (Luckily, they fixed that for free - good thing they keep server-side backups of every movable.sed from every system that goes online, huh?)
And while I could just reset everything, I would rather manually edit my N3DS' TWL Customer ID (at least, that's what Decrypt9 calls it) so it once again matches what's on my cart's save data. For nostalgia reasons, of course. I'll assume that hex editing is involved, but since this is a fairly esoteric requirement, it's hard to find the file and offset in NAND, as well as the offset in the game's file. To make this easy, let's just say that I'm trying to find it in Mario Kart DS, because that game's popular and I have it.
