forked from len0rd/rockbox
Start to implement some functionality. You can now read/write the entire partition (as ipodpatcher used to do), extract the original firmware to an "apple_os.ipod" file, or replace the original firmware with either a Rockbox bootloader or Rockbox itself. Adding/Removing a bootloader isn't yet implemented.
