Mmmm... as far as I know the ff8 pc version is using some gfx library which takes care
that the game is working even on cards without pal texture support.
Well, if you are using a GeForce card, you have to use the GF FF8 patch to get rid off
misaligned textures... worked for me, but of course I haven't installed the game anymore,
so I can't say if the new det's are messing something else up.
