Oh yes they are. The upgrade firmwares are (at least in the X5* cases)
unencrypted so you can start your disassemble adventures right away! ;-)

Sorry, bad use of words on my behalf. I meant buttons. Having Rockbox without
being able to read/scan buttons is... a bit lacking! ;-)

Even better! On the X5 you can upgrade to a totally broken bootloader in
_flash_ but when you mount the player to your PC and put the upgrade image in
the correct place in the FS you can still upgrade to that. Ie, we cannot in
fact destroy the player by flashing a bad firmware on it. At least not to my
knowledge. Don't feel obliged to prove me wrong! ;-)

BTW, we should probable take further develop speak to the rockbox-dev list
instead...
