Soooo, I am somewhat of a noob when it comes to CFW so you'll have to try to bare with me as I try and explain my issue and hopefully we can come to a resolution.
First off, I am currently using Luma 11.2 and a Gateway. I realize that updating my firmware to 11.3 will break the Gateway so I have not done so. However, when I was just using my gateway and nothing else (before CFWs were a thing) I was able to use an Emunand function that could go to any version of firmware I wanted while keeping my base firmware at 4.5. So I tried messing around with Luma's EmuNAND changing the style to see if it saved the style for one NAND differently than the other. I am just unable to see any difference between an EmuNAND vs SysNAND. I have no idea how to tell if I am on an EmuNAND. The only difference I can see is one says sys and one says ver. I assume the ver is the one I am supposed to update, but I think that updated my SysNand last time I updated it.
TL;DR
Anyway, once I am on an EmuNAND, am I able to update to 11.3 and keep my SysNAND 11.2 for my Gateway? That's the main question out of all of this, I'd just like to be educated to this point so I have an idea of the ongiongs of the hardware/software.
Any help would be greatly appreciated, sorry I'm new to the whole ordeal.
Oh! Also, how would I go about turning my legit .3dz files to .cia while keeping all of the private header information, or do I even need the private header information anymore?
