Need assistance on modding. 7 materia

I very much appreciate the time you took to look at this post, but I have a matter that I would like to get helped with. In the materia section of the program there are 11 unused materia (dummy materia). with proper programming you can take this materia and edit it to have any name or skill you wish. the problem is i have no idea how to get that into the ff7 game with out going to the debug room, which we all know needs alot of debugging lol. i know bad joke. right now I made have a materia i want in my game so i can Mod and test it with having to die. it has all the helpful stat effects on (shield,reflect,haste,both barriers,regen.ect) and meteor, ultima, bah. zero, full life and odin. is there a program i can use to maybe add that ass clouds starting materia? or a better scene editor that accepts those dummy materia as drops or pick ups.?

im in the middle of a massive storyline,skill/equipment name, and scene edit and im getting tired of long fights.
any help would be appreciated.

btw i have my buster sword edited to a max 255 on all stats and drains all elements but health and has triple growth for materia.lol. thats fun.
