The 12.40 drivers are for real. They are unoffical beta drivers, that is why you won't find them on Nvidia's site. Just because they are betas doesn't mean that they don't work as good as offical releases, they do. They are fast, the fastest I've seen yet and the colors are more vibrant. They are worth getting.
UncleClive, unfortuneately, I do not remeber the link either. But it is really not necessary. All Betamax has to do is use the new 12.40 Detonator drivers w/his card. His card will then do software rendering fast enough to make it look like hardware rendering. It will be plenty fast enough for FF 7 PC and the 8 bit palatized texturing won't even be missed.
