Hey I need some help here. I'm playing Final Fantasy 8, and I want to remodel squalls gunblade. I got the nessessary parts, but when I try to get "revolver" it says "You already have it."

If I already have it, how can I get a better remodel? Like, It only gives me the option to remodel to "revolver". How do I remodel to a model thats BETTER than revolver?

You get plans for weapons through out the game in battles and stuff. Oh, try and draw from as many bosses as possible. Its a way to get a lot of Guardian Forces.

What we can loot from all the forces?
