Please 

[karashata]

Ports aren't planned, they're worked on when people who own the player take it into their own hands to do the research required to make a port a feasible idea. Such research includes finding out what components make up the player (things such as the processor and memory, the audio codec, the screen, and other components), how the original firmware is structured, how the firmware upgrade process works (if firmware is even upgradable), and other things necessary to make porting Rockbox possible.

There's more information here.

One other thing: What player is that, exactly..?

The guidelines ask that you use English in the forums.  I think karashata has provided all the useful guidance that can be provided about this now.  Since this isn't a Rockbox supported player, I'm going to lock this.
