It could only work if the Pico also simulates a  graphics card. (Which might be a great feature).

Yes,
Video ram can not be simulated.
And yes, video is planned for the final board

what if vram is shadowed onto the pico/mcu and then the RGBS sent out from that?
it could be enhanced for scroll etc without writing to internal vram

If I got you correctly that's not possible, as VRAM can't come from "outside".

Didn't someone here have a separate mod that used the 2nd 64kb ram instead of the first in a 6128?

That doesn't matter. The GateArray can't access any RAM that isn't physically part of the mainboard RAM circuit. It can be done for the secondary RAM bank of the 6128 as that RAM is also part of the RAM circuit.

If you want anything else you either have to heavily modify the mainboard or generate the screen image without the GateArray - what a Pico"GPU" could of course do.

Ah thanks for clarification, I wonder... like some amiga hardware, could a hardware into the cpc CPU socket as well as under the gate array to facilitate some of the limitations? [Off topic to pico RAM I guess]
