I happen to love all of the class change looks, actually. Except maybe the Ninja. He always looked like a red football player to me. I don't like the class changes in the remakes as much because they still look... childish. It's cooler in the NES version because they look like cool and awesome adults. And the remake "Black Wizard" looks laughably ridiculous.
I downloaded a version of FFHackster, but it sucks and does not work. So, if you could please give me some kind of link, it would be awesome. Or at least tell me where this "missing DAT file" is.
