(Please just correct where I'm wrong or loose touch with reality.)

Well... Won't re-engineering the code offer any clues? I mean, the research
notes indicates that the MPEG outport port pins are known. Given that, the
code has to use them to make sounds.

To make sounds, it has to use mp3 data. To get the mp3 data it has to read
the disk...

Given that the CPU has DMA, we might get some details by checking out how the
DMA is controlled and check the code for DMA activity (assuming they use DMA
for at least some parts of the above).

Or am I out in the blue again?
