Hello all,

Been a lurker here for a while and have some questions about hacking.  Is there an (easy) way to take an existing formula hack, and perhaps alter the offset so that it affects a different formula?  For instance, there is this hack made by Emmy below:

<Patch name="Formula 2A - Power Split">
    <Description>Will average PA and MA stats with target.  In the case of odd numbers, difference favors the attacker.  New version - better for general use, and works with Contrary/new Finger Guard code.</Description>
    <Location file="BATTLE_BIN" offset="1229a4">

I'd like to use this in the game, but don't want to overwrite the existing 2A formula, but have it replace, say, formula 27.  How would I go about this?

Yes, it's quite simple.

Watch this tutorial : https://ffhacktics.com/smf/index.php?topic=12477.0 : at the beginning of the first video Xifanie point to three formulas. You just have to follow the same steps with the formula you want.

Thanks, think I've got it figured out now.  I didn't know about the formula table on the wiki that showed the locations of all the formula routines.
