The user in the vids uses a gil-changing PAR or gameshark code on the game and gets TONS of FREAKY results I did not know where possible.
As In you can control any texture in the game, the gelinka, ruby weapon, emerald weapon, junon cannon, underwater reactor, etc.
There are also multiple copies of the underwater areas.You can even talk to highwind members as cloud when your supposed to be tifa when clouds sick in mideel.
Not only that, you can control Red, and upon entering the room he is already scripted to be in, you start at his position, not the door...
Check all 4 vids out and tell me your analysis.
