unable to save ingame: monster hunter freedom unite.

I had a similar issue with Portable 3rdHD while messing with saves. Be aware that this could not work with unite, but I'll post it anyway. First: backup both savedata and savestate folder from the emu in order to lose/corrupt savegames, load your game as usual, when you attempt to save and that message pop ups, if it ask to delete the save, do it, and it should ask you to save again on a new slot.
