While researching whether my shiny new 770c could use Rockbox I came upon
this website. Evidently it's an unsupported build; installation instructions are a bit sparse (none for the 770c specifically,
or for any OS other than Windows), although someone on Head-Fi provides some slightly better ones
here, and it's not mentioned in the Rockbox wiki at all.
It would be really nice to have some better firmware for this thing, but I'm extremely wary of bricking an £85 music player. Am I worrying too much?
