Quoted from lucky1:
You can either use the pin2dmd editor or pin2dmd.exe to generate a 4 color custom palette and copy this pin2dmd.pal to the sd card.
The system will use these colors for the game.
I´m not sour at all. I like this project. You are right the pin2dmd proof of concept started as a vpinmame device using the pinDMD protocol which is part of open source VpinMame code but we are far beyond that now. Until now I don´t understand why you did not use the same protocol and same hardware for pinDMD3 but maybe using a modded version of Teensy FadeCandy seemed to be the quicker solution. I´m still happy with the current 168Mhz STM32F407 and its 210DMIPS which is only slightly slower compared to the 180Mhz Kinetis K66 with 225DMIPS of this project.
Surely you mean the open source, not for commercial use without permission code, right?
Yeah, I don't think stealing and using the code commercially can be dismissed that easily. Nice try, though.
