You do not want to combine a Geforce card with the FF7.exe from the patch....it'll crash. The only time you use the FF7.exe from the patch is if the 8 bit pallet says failed. And the only way to do that with the new Det drivers is with Rivatuner......
But it's much simpler just to use the FF7.exe from the game....with the FF7config.exe from the patch.....AND.....this is just to get 3d Acceleration to work. Not to keep crashes away. If your game was crashing in Software Mode, before trying the patch.....YOur problem lies else where.
Now...let me get this straight.....the FF7config was crashing before that? Because that should work fine. Are you using WinXP? I don't have much experence with WinXP and FF7. I would suggest to use Win98SE with FF7PC, as it's more reliable.
Search the board for WinXP and FF7. You'll find workarounds. I just can't recall them on the top of my head....Something about compatibity mode and stuff like that.
