I've used Rockbox on my iRiver H340 for a while now and love it!
I recently ordered a Meizu M6 "miniplayer". http://en.meizu.com/product_m6.asp
Of course "What about Rockbox? I would love to stick with it!" came to mind.
Searching for the player I found the following thread (has been locked):http://forums.rockbox.org/index.php?topic=7430.0
It apparently contains a link to a pic of the innards of the M6:http://my.opera.com/inokia/albums/showpic.dml?album=83493&picture=1088876
It also contains an outdated link to a page that supposedly states that the CPU is the same as in the iRiver E10, which is also mentioned in this thread:http://forums.rockbox.org/index.php?topic=4291.0
I'd really like to see a port to the Meizu M6 happen, and would be more than willing to actively work on it and do some heavy time investment, as well as limited money investment (for development players etc.) as soon as I am convinced we have a team that can indeed tackle the problem at hand, and have enough info about the hardware, or at least rather reliable methods of obtaining this info.
I would consider myself an average programmer, and have never participated in anything like this before, so more experienced members would most definitely be needed to see this port through. I have coded a bit for the Nintendo DS, but nothing big (yet). I would see such a project as a possibility to enhance Rockbox compatibility, and of course, to have fun and learn a lot at the same time.
If you are interested in working on such a port project, I would be quite happy to hear from you!
