Stat Cheats for Co-op With Custom Character

I've been playing Legend of Mana in co-op for a bit, with each of us using our custom character. I'm player 2 so I don't always get to use my character, and when I do I can't change her equipment or STs.

In order to keep my character's power on the same level as my buddy, I would've had to play through the game on my own as well, to unlock new moves, STs, and shops. I didn't want to do that so I looked around for game shark codes to save me some time and let me stick to experiencing the game with my friend.

I found codes online for all the STs and infinite money, but not for instantly unlocking any weapons or armour. I wasn't able to figure out codes for unlocking them either, but I developed codes to set some of your equipments' stats which works for me.

Here they are (activate and try switching weapon/armour if nothing changes):
Set equipped weapon's damage (replace ?? with how much damage you want)
8004363C 00??

Set blunt defence for armour in slot 1 (replace ?? with how much defence you want)
8004367C 00??

Set slash defence for armour in slot 1 (replace ?? with how much defence you want)
8004367E 00??

Set pierce defence for armour in slot 1 (replace ?? with how much defence you want)
80043680 00??

Set magic defence for armour in slot 1 (replace ?? with how much defence you want)
80043682 00??
