Quoted from roar:
Was it working before/does the previous code work?
I was struggling getting it working with a new PIN2DMD but it turned out I had a bad MAX232 chip on mine so it was a hardware issue not a software issue.
Yes and no - I had the 1.70 code working perfectly on my old MET I sold several months ago. That one sold with my old pin2dmd installed. I just acquired a new MET last week, with newer pin2dmd, and the 1.70 code works partially. Some screens changes palettes perfectly (like the snake, coffin ball lock, MET letters, Sparky, and many others). Others (like the main score numbers, lady justice, etc.) do not correctly change palettes. They simply use the last palette loaded. When I update to 1.80 code, it will not change a single palette - it only uses the "default" palette.
Do you think this could be a hardware issue? And if so, why is it working SOME of the time? Thanks for your help.
