B2W2 Move Damage Calculation Modifiers

[Alses]

Secret Sword, Psyshock and Psystrike all use the user's Special Attack Stat / Target's Defense Stat instead of the regular attack/defense so I was wondering if anyone looked into how to recreate similar effects such as Attack/Special Defense, Defense/Special Defense, Special Defense/Defense, Attack/Special Attack, Special Attack/Attack etc. You get the idea (Could've included other stuff such as stats combined and the speed stat in there but wanted to keep it short and simple), so does anyone know about what data commands the way to calculate? I've not modified any moves in hex so help for where to begin looking is nice. Thanks!

As for how moves act... dunno. You're best off looking at the hex of each move and figuring out if there's any bit flags that do that.
