I have a Unisystem PCB with SMB running on it. I also have it running on an RGB LCD monitor and piped through an original Nintendo inversion/audio board.
Everything plays fine and all the color adjustments work well too. The only issue is that there are vertical lines on the entire screen (more prominent in the darker colors) that should not be there. Its not enough that you cant play and enjoy the game but I would like to fix it if possible. I have ruled out the monitor as it plays other boards without issue. I have another Nintendo inversion/audio board that I swapped out and it did not improve. I am pretty sure its something on the main PCB that needs repair but I am not sure where to look. Any help would be appreciated.,
Thanks,
