I was on emunand and was playing MH4G. The 3DS ran out of power so I had to do the regular process again. However, when I tried going into gateway mode, it asked me to update the 3ds gateway card so I did. Afterward, it was a black screen, I turned the power off and did the process again and got into the game successfully. However, there is no game save!? Does updating wipe game saves or what?! Can someone please help me, I got 50+hrs of game time already! There was no warning before updating that it will wipe game saves!
