We all know there's unused 'blank' materia in the game, and ive decided to mess with this for the upcomings of a mod or some sort ive been working off & on for awhile. now, i can use WallMarket to actually make it have a name, i edited a blank spell slot and gave it a name, everythings peachy keen in the materia window, it says <name> it's highlighted and it's pretty looking (lol). but when i go into the check magic, or enter a battle it isn't selectable. i reason this because since master magic is supposed to contain all the spells, that there are no slots available for it to be selected. and i was curious if there was a way to edit that. on top of it, at one point i made it look like Pulse of Life on a random enemy/character (idk how i managed that) but it did 0 damage and didn't do anything else, but it looked pretty lol. this is for the PC version of FF7 btw.
any and all help would be appreciated :3
