yea the icon changing is bizarre. I think it would be worth looking in the icon images folder too in order to see if the files are being renamed or created with a different file name. for ex, did it take the Sega Dreamcast icon and rename it to All (in the end basically deletes having an icon named Sega Dreamcast), or did it create a new All file that happens to use the Sega Dreamcast icon image? (Sega Dreamcast icon still exists in this case, and it would look like there are two icon images for Sega Dreamcast, but one would be properly named Sega Dreamcast, and the other would be All)
