I have my external HDD set up for FAT32. At first I thought cios249 could not be used as a default cios. Can it be used at all from Configurable USB in FAT32? If not, I am thinking of dumping my external drive back up to the laptop and reformatting it for a WBFS partition so I can use 249 again. Is this necessary? Is there another way without the full swap? I am worried that I will loose the extra compatiblility of cios 249 for some games.
