I'm excited for the Adafruit Fruit Jam to come out. I don't know how much it'll cost, but it's really a complete small computer: 2x USB A for keyboard, mouse, and/or controller, HDMI, SD card, high quality audio out 5 RGB LEDs, extra PSRAM, and some other goodies. I imagine it will be quite straightforward to port this.

While getting DVI/HDMI out from a RP2040 is an impressive hack, on the RP2350 it's pretty straightforward, and the chip will do standards-compatible 640x480 without overclocking. With overclocking, at least the one I have will do 1280x720 60Hz (albeit with reduced blanking). At those resolutions and the limited amount of RAM, framebuffers are not great (this is why bpp is so spare), so I'm exploring generating video on the fly.

Super fun chip, I highly recommend it for people who want to get into very low level programming.

PicoCalc from Clockworks looks interesting too - a portable Pico computer (keyboard, display, GPIO, ...).

I was disappointed to find that half of the monitors and TVs I tested don't show 640x480 HDMI though all of them worked at 1280x720.

So I am redoing a project I am working on to use the higher resolution.

Good starting point video -
