earlier today i tried to update my template file and write a new copy of MH4U with a new header. I did a backup of my old save before i did so. After i copied the rom with Diskwriter i restored the save from the previous header which is completely different. As i mounted the Rom i got an error saying "Cannot Read Card". but the rest of the games were still working, Until i formatted the whole SdCard and flashed the header with the new one. Now big games like LoZMM and MH4U has the same problem. Except games like Super Mario Brothers 2 and Cubic Ninja still runs. So far i have formatted everything, My internal Sd. Reset the system. Formatted the Sky3ds card. Changed template back to original one. Nothing seem to work. It has been 4 hours now and idk what i did wrong Please guide me through any solution possible.
