I'm a newbie, and this will probably sound like a really stupid question. I have a firmware upgradeable mp3 player I bought in China (www.mscmp3.com or www.vintion.com) and I've looked at the binary code from a .rom file. I've been trying to find an SDK or something like that for the mp3 player (so I can play with it a bit). Searching strings from the file (error messages such as
"Illegal instruction (call to non-function/code corrupted)
[is the floating point emulator installed?]"), I came upon openzaurus' site. Can someone tell me if this is the right place to be; is this the software I'm looking for?

Thanks for your patience in reading such a long, possibly ridiculous question.
