Boss battles have infinite battle item usage

DaimyoHermit, Mar 29: Is there a possible way I could make them infinite? The only way I have thought is to edit the battle scripts and find the code where the battle item is reduced to 1 then changing it to 0 instead of 1 to make it infinite.

McPaul, Oct 29: It's easy to raise a Pokémon's base stat by 31 to emulate 248 EV in this stat. But some are not possible to maximize this way such as Blissey's 255 HP or Shuckle's 230 Defenses as a base stat can't go higher than 255 unfortunately.
