New Parts arived:

N64 Extension Cords and 4rp2040 pro micro

I flashed the pi picos with https://github.com/pdaxrom/usb2n64-adapter and tested everything on the real thing. Works like a charm.

Next step will be the N64 AV to hdmi converter to use the Video output of the N64 with the 2x2 Matrix controller.
