Just playing Super Mario All Stars on an RGB matrix panel as you do.

To keep things together better, I 3D printed a bracket in two pieces, the subject of a work in progress playground note: adafruit-playground.com/u/jepl

This is using a 3rd party breakout board with 3 HUB75 connectors. I recently added the ability to drive up to 3 connectors to Adafruit Piomatter, as well as temporal dithering.

In this specific interest, I'm using 2 connectors to drive a total of 4 64x64 panels. --num-planes=6 --num-temporal-planes=2 means I'm getting effective 18 bit color, albeit with the least significant 2 bits being shown on alternate refreshes, creating a tiny amount of 44Hz color shimmer.

All these "go faster" tricks together give me about 88Hz refresh rate on the panel, despite that we're still limited to about 10MB/s of data between the PI's main CPU and the PIO peripheral that's acting as the LED controller.

A bright pixelated LED panel shows the World 1 map in Super Mario Bros 3. A SNES style controller is sitting on top of the LED panel. On the right a red PCB with 3 connectors (2 occupied) can be seen. This is the "Active3" adapter. Under it (with just a few features visible, such as the USB ports) is a Pi 5. All around on the wood desk are pieces of electronics from those other projects I just never manage to tidy up...
A view of the back of the matrix. You can see 4 individual sub panels held together by a white plastic 3D print. There are ribbon connectors and power cables, making the thing a bit of a rats nest. As in the other photo, it's on my messy desk with a dark wood finish & lots of unrelated wires, PCBs, tools & more.

The Register's page on deploying a Pi-Hole 6 to cut out advertising crap is interesting stuff given the vile behaviour of browser companies over recent months - theregister.com/2025/03/08/pi_

The Pi-Hole website says you can buy a complete kit for this from The Pi Hut - thepihut.com/products/official

I'm tempted.
