Hmm, glancing at the "Product Letter" I have, it does mention "Enhanced
Multi-Media Architecture" so I'm guessing its an EMMA SoC indeed.

Do you have to part number?

Did I not send one?! It must have been late...

It's a uPD61032, marked D61032GL on the chip. The exact markings are:
NEC JAPAN
D61032GL
9949EK019


That's indeed the EMMA.

Now we know what it is...where do I find the docs?

There's a couple of 2MB SDRAM chips just next to the CPU (both from different
manufacturers, and with different pinouts, interestingly enough), 2 Amtel 2MB


IIRC, there's a separate 2 MiB SDRAM for MPEG decoding.

That would explain it, I guess. What that means is I have all of 2MB to play with then :-(

Gr{oetje,eeting}s,

Cheers,
Chris
