I was browsing the link above
Seens they figured out the processor was jz4755 just as darfgarf said (lucky guess? hmm)
And the frontal USB ports aren't USB... If you connect the controller to the PC, it doesnt recognize/does nothing.
And i think some guys are almost hacking it there.
Read for yourself if you didnt understand anything i said.
@edit
Ive been browsing trough the PDF file here, documentation from jz4755...
Seens interesting, has a CPU, and VPU...
XBurst CPU
− XBurst
®
RISC instruction set to support Linux and WinCE
− XBurst
®
SIMD instruction set to support multimedia acceleration
− XBurst
®
8-stage pipeline micro-architecture up to 360MHz
What can we do with that?
Operating frequency is the same of the dingoo (400mhz)...
Nothing more of interesting that i could dig up, and the guy on the other forum also found that out i see.
