Suggestions on adapting to a 65C02

[cbmeeks]

Regarding this topic I started a while back (https://forums.raspberrypi.com/viewtopic.php?p=2074436#p2074436), I'm interested in interfacing the Pico to a 65C02 computer I am building.

At the moment, I really only need the video output plus interfacing to the 65C02's bus.

So my question is, do you have any suggestions on a "minimal" installation of this? Meaning, what would be the minimum code I would need for my goals? For example, I don't need any audio or keyboard, etc.

Any help would be greatly appreciated.

Thanks!
