As a result of a loose battery, the system clock on my 3ds is completely off in both sysnand and emunand. I want to go into system settings and fix this, but I'm worried about overwriting the DS profile exploit, as I don't have a copy of OoT handy. My friend had his overwritten when he changed his 3DS username in emuNAND, and I'm not sure if changing the time will do the same thing. Can someone give me an overview on what can and cannot be modified in order to keep the DS profile exploit? Will modifying the time in emuNAND cause problems?
