/*
    I wrote this program one evening when I was going through iNES serial numbers
    and I got tired of using ResEdit.  This works for iNES 7.7, though it doesn't
    really matter since someone cracked it.  It probably won't work for later
    versions since they'll change the hobbling scheme and I have no idea if it works
    on earlier versions (besides, if you're using an earlier version when 7.7 and the serial
    is available there's something wrong.)

    This assumes the prefs file is still invisible, locked, & in the prefs folder.
    If it's not, then the app quits.  If it is, it unlocks the file and deletes it.
    This is a little bit of a pain since you have to retype all of your settings
    (but not as much of a pain as unpirating iNES manually.  If anyone feels like
    it, they should update this so it fixes the prefs file without deleting it.
    It shouldn't be that hard (look at the a clean pref along with a pirated pref)
