As I'm tyring to learn how to use pokeemerald, the oldhags will like this try to make Emerald stats like GSC. I managed to make all stats maxed out (no EV limit, all EV can get maxed, vitamins like Calcium all give 16 EV each up to 160 EV to give the same effect as GSC too, SPA and SPDEF have the same IV and natures are all neutral.)
But the last thing to do to GSCize Emerald stats is to delete Zinc and make Calcium raise SPA AND SPDEF at the same time. So the item's code got modified like this:
The problem here is that now the Pokémon can eat 20 Calcium instead of 10 and one stat gets raised THEN another instead of the two at the same time.
How could the two of them be raised at the same time with only one Calcium?
