USE A GAME SHARK!
that's it, that is the ONLY way to get her back, she is DEAD.
i hate it, you hate it.
we all want her back in the party, we all want to kick Cloud in the nuts for not tossing a pheonix down at her after she died.
(yeah, its' second nature to cast revive during battle, but during a vs?)
ok, please sticky this post.
if anybody tells you you can get Aeris back in you party, kick them!
kick them hard!
ask them if they've done it first hand! it can't be done!
the glitch/cheat/tactic in the game that brings Aeris back to life without using a cheat device DOES NOT EXSIST!
AERIS DIES! DEAL WITH IT! PLEASE STOP SPREADING THE RUMORS!
THE RUMORS LIE!
you can't use tissues in her room and revist her grave to bring her back, you can't force her out of your party before she dies and put her back in after disk 2, you don't run into her anywhere on disk 3, and, although you can see her ghost at the church, you can't drop a PD at a correct spot to bring her back.
oh, and if you acually believe that had a memory card with 99 games saves from disk 3 with your party at lv99 can start you a game where she doesn't die, YOUR A RETARD FOR THINKING A MEMORY CARD WITH 15 SAVE SLOTS CAN HOLD 99 GAME SAVES!
thank you for reading my rant

i loved Aeirs as much as the next FFVII fan, and i would love to find a way to bring her back to life, but if she didn't die casting holy, holy would not have cast, and Sephy would have killed everyone and won.
it was the spirit of Aeris that made Sephy weak enough to be killed by Cloud, not team work, and the holy materia with Aeris's spirit that stop meteor.
so please, no more rumors about bringing Aeris back to life.
