Is it using the 1.3-inch monochrome OLED display of the Arduboy or something smaller? (Guessing the 72 × 40 display of the Thumby?)

This is for 72×40 display right now but I was also working on an interface layer to abstract Thumby specific functionality in order to play on potentially other platforms running MicroPython/Python. Going to try and add that in the next iteration.

There are a number of MakeCode-compatible devices with and without Microbit https://arcade.makecode.com/arcade-devices

TIL RP2350 support DVI video output with an HSTX: https://www.google.com/search?q=rp2350+dvi

And it's possible to convert from DVI to HDMI

> The new HSTX interface on the RP2350 seems to be squarely targeted at this use case (video output) and doesn't require the use of PIO or consuming a ton of CPU cycles. There's a nice write up on the capability here:

This is cool thanks for sharing! I'm definitely be digging into these. It would be neat to support some of these devices too. I didn't know about MaplePad (+1 to Dreamcast VMU projects!)

Following up here, I just added a game interface abstraction to make it easier to support more devices. Planning on getting a few MakeCode-compatible devices to adapt for them.
