I can't get the scroller to display anything except complete garbage. No text at all, just a bunch of garbage that looks sort of like deformed petscii graphic characters.
Think I worked it out. I was using a koala image generated by a converter program. The image displayed fine but the scroller was garbage. When I used a legit koala image saved on the 64, the scroller worked fine.
Hey, sorry for posting here, but I noticed in your recent Tony La Russa CRT that all the batters are standing backward at the plate. Could this be some form of copy protection from the source disk? Pretty crazy stuff.
