The game cries out for pure primary colours which are absent from Pico8's palette. I discovered I could force them to the LED matrix by reducing bits per colour in the driver.
Also:
- A Pi4 (I've tried a Zero2W but can't quite get it up to speed)
- A 5v 15a PSU
- Some IDC cables of different lengths.
- A 'HUB75' adapter
- A week of headache
thats pretty cool pubjoe ,love it , whats the pico8 running on the pi4 ? i didnt really process what was in the pic before as i was distracted by your stick
<trk>:I remember catching a big fat one and my friend said "throw it back in, that one already tastes like wood"

Yeah Pi4. Well, Pi400 but it's the same thing. It uses hzeller's LED library and Jenissimo's program which takes continuous screenshots of Pico8 to display on the LED matrix. I made a video to test my setup and joy_test.p8 responds after 1-2 frames of latency which I'm guessing is about the same as any normal screen used with Pico8.
These panels have a lot of potential for retrogaming. A 256x256 matrix would be great for classic arcade games. There's currently a program for Game Boy on LEDs. My 128x128 matrix set would use downscaling, but I kinda feel GB with its inverted greyscale / light backgrounds is one system that wouldn't fit so well. Maybe I'm wrong. Pico 8 is perfect anyway.
This looks amazing. I’ve not really looked into the pico 8 stuff much at all but Joe you’ve done a great job of showcasing it. I now want a setup and the Sanwa stick
Thanks. Everyone should have an LED matrix Pico8 setup. I still want to do some fiddling for the best way to keep the set tidy and contained.
Most recently I put the screen in a 19" arcade cabinet. When viewing this close I think it needs a diffuser so I want to try some of those options out.
I bought the Pasoko in 2022 and it cost a lot more than a two button stick is worth tbh. Cute though. I hadn't actually used it until this little project. I adapted to USB with a Pi Pico running GP2040-CE and set it to DirectInput. The stick has an internal cable connector so this could be done pretty easily and non-destructively.

^ basically like that but I realised that I had to switch a couple of wires around after taking the photo.
