I'm trying to get the game running with FSAA enabled, and after doing everything listed in 'The Great FF7 FAQ' I'm still getting gridlines in the background.

I have a GF3 Ti200 running the 53.03 drivers.
Maybe I screwed something up along the way. I remember reading somewhere, on a different board, that all I needed out of the 1.02 patch was the config file....having been a PC gamer for 22 years it sounded strange to not replace the exe when patching a game, so I replaced the exe with the one in the 1.02 patch. Was what I read on the other board correct? I did ask, but no one replied.
