Ok I hate kalm flashback, so I used speedhack at x20 to play through it. I was unaware you could control sephiroth in the hardcore mod(unless that too was a glitch) and we both got killed and I got a game over(during the flashback
So I load and head to kalm to redo it, and run into a battle. The battle ends(keep in mind I LOADED, and I am instantly back outside the battle that game overed me previously. I walk forward to the mako reactor and, Tifa steps out of my party when young tifa is still there!
I can video it from this point, or else try to recreate it if need be.
