Yeah, it's not an unique bug. It is a little annoying at first, but you get used to it. When you've beaten Ruby Weapon a few times using KOTR, the delay almost becomes unnoticable. Like it's part of the summon. The whole world stops, and then a bunch of idiots come out of nowhere twirling sharp sticks, swords, axes, etc.
As I have not said before: FF7PC is shite. If you wanna play it with no stupid crap, albeit the sketcy script situations, then play the playstation version. In that at least you won't have any incomatability, random crashes, pre-determined crashes (Hyper Jump crashes the game 50/50), whacky music if you have no psf's or soundfont support, and many other unmentionable POS errors.
Here's a new one:
Contest: Can you spot where that screenshot is located on the world map?! PM me or place your guess here!
See? Get the playstation version. Rob a blind kid, get it for 2 cents at a garage sale, nab it in your trenchcoat at your local computer software store, or any other means of getting it. Do it now!
