Cheers mates , my first time posting on rb forums.
Ok , so the player i'm talking about is a Sony NWZ E43x series [i personally got my hands on a 436F].
The player appears to be using a Sigmatel chip [maybe a 3600 , dunno for sure] and the firmware appears to be encrypted.
The firmware update program is done through a Sony-branded Sigmatel update-program-thingie [discovered it after dissasembling the .exe ].
So , altrough this might be against forum rules to ask , does anyone wanna start porting rb to this little thingie ?
[oh , btw , sorry if i posted some nonsense or stupidity , my skills don't quite match the job of rb developer]
Later Edit :
I have discovered that the chip is indeed Sigmatel based , and I'm also pretty sure it's the 3600 so this kinda makes rb development easy
The firmware structure complies to what is already available in the wiki , that is :
Using the Sigmatel firmware extractor i was only able to get "bootmanager.sb" out of the player , but what i've found more interesting is an update program that is not Sony-firmware bound , this means we can upload our own files to the player , the program can be found at http://www.maxfield.de/index.php?id=16&tx_maxproductslist_pi1
along with the firmware for that player [bricks the sony if you try to upload it]
Also , i've discovered that the player can be unbricked by the use of the original Sony update program.
Hope this will get someone's attention
