Well, what he described is basically patch-worthy. I think others earlier thought this was a slightly redesigned/improved version, the whole George Lucas thing, but it's just a bug fix and speed improvements. He says all he did here is, 1) fix a fatal bug, and 2) improve load times.
The thing about a patch though (if he made one), is you'd have to rip your original disc (with something like TurboRip), apply the patch, then burn a CD-R to get the benefits. Problem is a bunch of people here have the notion that a CD-R will rape the CD lens on original NEC hardware, so they're gonna want an original silver anyway if they care about these 2 improvements. If you know about the fatal bug and can get around it, I guess it's not that critical to you to care about this.
