Monster Hunter Portable 3rd HD

Hey guys small question about cheats like this one:

Quote:_C1 x99 Inventory Items Slot 1
_L 0x817AF800 0x00180004
_L 0x00000063 0x00000000

If i activate it, the items in my inventory are shown as x99. so far so good.
Lets take 1 bone for example: I take 1 bone out of my storage into my inventory and it shows up as x99. as soon as i store that bone again or disable the cheat, its back to 1. If i put it in my inventory and go to the blacksmith it also shows up as 1.
Am i doing anything wrong or is this cheat just not working anymore?

Using PPSSPP V1.0.1 Windows x64


edit: experimented further. sometimes if i keep the items in my inventory and then go on a quest or something, it will actually put x99 into the storage afterwards. sometimes it doesn't. its like a 80/20 chance
