Emulators 9.2 Quick Question

Hey, I read on some thread that emulators run better on 9.2 if you launch it as a cia rather than 3dsx (or whatever the file is). So I installed the cia to Aureinand and there was no physical difference in how the emulator runs from how I remembered it as a 3dsx file. Am I doing something wrong or should I continue to struggle with AGB firms and whatnot.

P.S. I'm talking about mGBA.

P.S.S. I'm on O3DS ...
