Hey guys and gals!
I have the stupid black characters problem too. I use a Macbook Pro with 8600M GT. Been at this for days now! I couldn't get it to work in XP either... And I tried a few different drivers... Well, with Vista, FF7 does work (so it must be a driver problem, right? Why can't nVidia fix it?!?).
Now the bad part:
1) I HATE Vista!
2) I don't know if you noticed, but Vista doesn't support DirectSound anymore (another reason why I hate it). Most of the time, you wouldn't notice, but there are some effects (like the "Cries of the Planet" in Buggenhagen's place) that just won't play.
You can google this (just search Vista & DirectSound).
Now, one possible solution is: I buy a "Creative Sound Blaster X-Fi Xtreme Audio Notebook" and hope that "ALchemy" (a little DirectSound-Emulator for X-Fi Cards only) actually does work.
Another solution is: nVidia fixes their stupid drivers for 8600M GT and Apple incorporates them to Boot Camp, so I can actually install them.
Another solution: I buy another computer that is OLD enough.
Well... I don't really like any of them! Anyone able to come up with a fresh answer to that?
Best, Rob.
