To some extent Ive made the Ice key 100% permanant in the game
download this savetate then save and quit the game. If you go back to the game, even without any gameshark codes you still have the key as an extra slot in the totals

still no image as of yet though, and it does reset if you actualy reset the game
I was basically messing around with runes slot codes on artmoney
savestate is a pj save
even after starting a new game, the ice key is still there after getting the 1st gold banana
