Need some help..

Hi!
I have some questions in making ff6 hack.
please help..

1) Can I make lore learned by item or magicite
but only leaned by if casted?
I searched offsets and tried this but still I don't know how make it possible..
Even ff3usme doesn't help in this case..

2) I can't change the character have natural magic.
I found how make it in this forum and tutorials but
As following..
Changing learing lore, swdtech characters work correctly
but chaging natural magic characters not...

I want to make locke(ID 01) known natural magic instead terra(ID 00)
and I changed the ID in two sections(C0/A182, C2/61B9).
At game start, terra didn't have natural magics (even has magic command)
So I thought it work correctly..
but locked didn't have NM also..
And After battle in narshe cave, natural magics revive in terra's magic menu..

There's somebody make it success changed or add NM characters?
Please help..

3) Short question..
Do you know where is weapon sprites?

I hope you could understand what i'm saying..
because I'm not native english speaker.

Thank for reading..
Have a nice hack!!
