Welp, got the resolution hack working, attempted to upload the christmas pack however the design_ui.xml doesn't exist in the 3.16.0 edition, only design_ui_z3.xml.
Edited the code of that one, uploaded aaaaaand.. stuck on boot screen.
I've gotten everything backed up including that file, but due to it being stuck on the loading screen it won't connect to WIFI, however FlirInstall is still operational.
So if anyone has a FIF that could replace FlashBFS\system\ui.d\design_ui_z3.xml that'd be faaaantastic because that is really all I need.
Edit: Nevermind I got iiiiiiiiiiiiiiiiiiiiiiiiit!
Recalled that a FIF file is just a renamed .zip file with a command file along with the files that are to be replaced, so I created my own zip file and edited the Camera.cmd file to match what was needed. Said my prayers, fired it up, watched in anticipation as the splash screen appeared... and then after a flicker the splash screen with the "This Product is subject to US Export Regulations" popped up.
Needless to say, I did a rather.. boisterous cheer.
