just replaced the firmware (think operating system) on my sansa fuze v1 (8gb model) with the open source rockbox. when using the sansa’s original software i was getting jumpy playback and i wasn’t terribly fond of the interface.
rockbox has a vast array of features and can be customised and fine tuned to suit the user’s needs and tastes.
the firmware, currently, only works with the first generation of the sansa fuze (v1) not the second generation (v2) so check your players version before attempting anything. it also supports various other mp3 players so see if yours is supported…
there’s an automatic installer available but i chose the manual method.
really enjoy using it so far. lots of features to tinker with and last.fm scrobbling support!
a couple of screen shots of available themes…
