FF6Tools - Browser-Based ROM Editor

Not sure where to ask, but since I can't find anywhere else or anything else relating to my question I'll try here.  This tool seems really awesome, however I can't get it to work.

Anytime I open any version of the FF6 rom, whatever change I make as soon as I save the application crashes and the changes I made are not saved.  Doesn't matter what change I try and make, it all just goes boom.  Any idea why this would be?

Hi sailor1337. I just found a bug that might be causing your problem. It seems to be a bug with the latest version of Swift. I made a workaround (since Apple doesn't seem to be working on a fix at the moment). Give this version a try and let me know if it works.

FF6Tools v0.5.1
