Hacking MT-Card Monster Hunter 4 Ultimate not saving

[RyviusRan]

I've noticed MHU is not saving my progress when inserting a header from one of my own games and changing the file to a .zav
Online works fine as I tested with a friend it's just saving does not work.

If I just play with the game with no header then saving works.
I noticed that when saving works the sav file is a large 4 gig file which is not like the normal save file of 3DS games which are less than a MB.

Anyone else having this issue?

If you are playing on emunand with firmware version of 9.5, try playing on an emunand with firmware version of 9.4 or lower

I use firmware 9.4

Edited my post to say 9.4.
I really wish I could figure out what is causing the issue and how to fix it.

Is anyone else able to successfully make a save file with Monster Hunter 4 Ultimate while having a header inserted to play online?
