:-D What do you use to disasm it, IDA? Hmm, the free version of IDA
doesn't support the ColdFire chip, I'm afraid...

It would indeed not be very convenient to have to ssh into the thing to
skip tracks... ;-)

If you don't mind, I'll leave that to someone else. ;-) This certainly
sounds like fun (so far all I did was porting Linux to WinCE-only
terminal devices <http://winterm.gaast.net/>, but it involved quite a
lot of reverse-engineering already)!

Done!

So now all I have to do is actually *buy* an M5. I just wanted to make
sure that I really don't need an X5. And well, if it doesn't work, at
least I hope the people at Cowon make better firmware than iRiver does
(at least for the iMP player, for example the iMP-550 had a habit of
randomly skipping some specific Ogg tracks when played in a playlist
(or something similar), while in fact it could play them very well if
you select the track manually).

Having open-source firmware on a music player really sounds good to me.
Like phones, music players always do something wrong, and at last now I
got the chance to fix it. ;-)

Thanks for all the information, and I hope to give some information
back soon then! :-D
