    Here's another [1] project that does VGA output from an RP2040 (the project also includes some game). There's also some support for VGA in the pico_extras [2] repo.

    This reminds me of the Uzebox [1], a video game console based on an ATMega644, but the RP2040 in this looks far more powerful at a glance. How far could this realistically be pushed?

    The PicoMite VGA project does something like this as well but has the added benefit of having a very full featured BASIC interpreter built in.

    OT but a question I'm curious about: what features would people who have a lot of experience with the RP2040 like to see on a successor?
