Hey jsm,
just a little observation i made the other day regarding that problem with the folders being inaccessible. I still havent gotten around to that reformat, but after a minor virus problem, i had to run norton. I observed that the scan was able to read all of the rom files in my folders that "don't exist." It even had your undo.bat, so I at least know that part worked... lol. Anyway, just found it odd that norton antivirus was able to still scan those files so i thought i would pass the info on to you.
