I bought a N3DS XL off of amazon a while after it came out. I downgraded the system to 9.2, got ReiNand working, everything was fine. Well, it wasn't really, the camera didn't work, but I could live with that. about a year later, I decided to replace it. I have a mediocre understanding of electronics, so I was able to (I suggest you don't attempt to do it on your own, it was a living hell). Fast forward to yesterday, I boot up smash and attempt to add an amiibo, but it doesn't register. I realized that I disconnected the NFC pad. so I took it apart again to connect it, what could go wrong, right? well, it won't turn on. I've given up. So here's where the EmuNand question comes into play. Could I take my micro sd card from my dead system and use it in a diffrent n3ds? Would it be possible to 'merge' the original EmuNand with the new SysNand to trick the system into thinking it's the right Nand? honestly the biggest problem is I beat pokemon moon and I didn't back up my save.
