like i said :P i'll get bagged ...

you need ff7 to be running on a personal computer, either by ePSXe and emulating the playstation version. OR just using the pc version of FF7 (remomended)

the play untill disk 3, and then download a program called "Jenova" from http://www.qhimm.com/ (its a ff7 pc save file editor) ... which will allow you to change anything about your save file ... add materia, gil, ex, lvl's, weapons, items, chocobo stats, new chocobo's, AND ADD AERITH TO YOUR PARTY !!!

now i don't want to be mocked, this does work ... if you don't like it, then ignore it ... if you want Aerith back, give it a shot ... i just done it and i now play with Aerith by Cloud's side in disk 3, and i swear upon my life that im not lying
