Not sure if anyone will ever use it :)
But just since it always bugged me, I think I've gotten the Editor for the original FF working on modern Windows PCs.
It required some hex editing of the level editor file, but looks good so far. I've packaged the whole thing up in a new installer and included the original Character tool (2 versions of it). If anyone tries it out, let me know if it works. Grab it on my Goodies page.
