My FFVII Game
This is my FFVII game that I've been playing.  It has 3 master magics, 3 master commands, but no master summons.  Sorry, I couldn't get a gold chocobo.  To load this in your game, copy it to the save folder in the ffvii directory.  You should probably rename it so that it doesn't erase your other save00.ff7 file.

Final Fantasy VII Game Editor
I received this editor, and was immediately impressed by it.  You can edit stats of characters, quantity of items, stats of chocobos, create new chocobos, and much, much more.  The only Final Fantasy VII editor I've encountered.
