Cyan 644e96b2d9 * Changed partition detection for DIOS MIOS to allow logical 
partition located before primary partition. (Thanks RCJayce)
* Changed partition detection for Nintendont to allow logical
  and primary partitions before the first FAT32 partition.
  (ex. NTFS primary+FAT32 primary)
* Moved IsWiiU() function to sys.c

* Fixed French language file
