You know, with the apparant frequency that this problem rears its head, perhaps it would be wise to incorporate a feature into Jenova (or any other editor, or heck, a completely new program) that allows one to advance his save file past the lockup, so that he won't necessarily need to go track down someone who can get past it for him.
Now, I've never used any FF7 save editors, but I guess something like that is already possible, but what I'm going for here is some sort of scripted hacking sequence for these specific portions of the game that are crash-prone. Like, a dialog box asking you which problem area you' like to advance your save past, and it'll automatically do the edits.
