Do theses player are supposed to work with Rockbox

[pascal06]

Hello everybody,
I would want to replace my venerable Sansa Clip zip by a more recent player but always with a micro SD.
I found theses player in France from unknown (at least for me) brands:

https://www.fnac.com/Baladeur-MP4-Bluetooth-Djix-C100-avec-clip-sport-360-Noir/a16294068/w-4
Do you know if they are clone from known brand's players ? Can they work with Rockbox ?
Thanks a lot in advance.

Most clones are based on really low end, barely programmable hardware with too little memory to do much with. You'd have to open one up or dig into a firmware file to be sure though.
