Thank you so much for the comments. I did do a hard reset (pin 30 to ground) as well as a power off; no joy. I've looked through the forum; but I'll try again. I guess I'll hook up a Pico Probe to see if that gets me any closer. It still seems odd that all the other programs work except Doom. Maybe there is some logic in Doom that looks for something (I don't know what that could be) and if it doesn't see it; then it stops execution. And it had worked so well; on the same breadboard; just a few days earlier.
