Hi,
I've have a device based on SPMP3051A. I believe it's practically identical to SPMP3050A.
I'm interested in getting alternative os(probably Linux or maybe something lighter if ram is not enough) running on this.

I have collected some pieces around the net and have pin layouts of the chip and description of the USB interface(comes with frm pro also). As well as some interesting code that pokes the device through USB.

My plan would be to get modified Nintendo ds emulator to run the firmware and then use the emulator to reverse engineer rest of the chip. I am not interested in working to extend the supplied firmware.

I have mostly concentrated on reverse engineering Ati 3d cards and dvb-t sticks so far so this is a bit difficult thing to do just by myself.
Having someone with ARM9/7 assembly knowledge would help with this a lot.

I use Linux to do my coding so ideally Nintendo ds emulator used for the task should be Linux based.
