Communication problem between the MPU and video RAM on the DMD controller board. To confirm, try running a display test from the game menus to the end and you'll get a report on reads/writes to the video RAM.
Can usually be fixed by reseating (or replacing) the two wide ribbon cables that run from the MPU to the DMD controller board.
Don’t reflash the ColorDMD. It’s not the problem and not in the link that’s causing the page error.
If you have another WPC game, next step is to swap the DMD controller boards to see if the problem follows the board. It could be a failed video RAM or a bad header connection. More commonly it’s the RAM.
On the MPU it could be a poor socket connection at an IC or bad header connection.
It’s usually a ribbon cable or the video RAM.
