FF7 froze right after I beat Ruby Weapon.
I didn't have a lot of trouble killing Ruby. I just set up all 3 of my dudes to be self-sufficient and then beat him with the one that stayed. You can of course cheat and give all your best crap to one dude, then make sure he's the one that stays behind.
That's how I did it. Wasn't that hard by the time I got there, no, but really irritating that I had to do it again.
I had a lot more trouble killing Emerald, because of that attack that does damage proportional to the amount of materia you have equipped. I didn't know that was how it worked, and I was fully decked out, so whenever Emerald used it, my entire party died. So I used the CounterSummon-Phoenix route, and spammed KOTR. Lame, I know.
Right, Final/Phoenix was the way to go. Spamming a shitload of maxed-out Counterattacks is good too, unless I'm misremembering and thinking of Ruby.
firefox crashes most of the time when there are flash videos playing (including advertisements or embedded youtube videos or whatever) which is pretty awesome! I'm not sure why it does it, and reinstalling the browser and the flash plugin does nothing, so that's cool.
Hum. I have that problem too; I assumed it was because I was running Linux (and 64-bit Linux at that), whose Flash support is not exactly stellar. (Ever see a Mac Pro slow down to the point of uselessness just from browsing the fucking Web? I have!)
Flashblock is a pretty decent solution; it doesn't load any Flash embeds until you tell it to. It's really cut down on my crashes, though I DID get one lockup yesterday from a page that had multiple videos on it. The Terrible, Horrible, No Good, Very Bad Video thread, IIRC.
