Hi, I’ve just discovered VICE and CCS64 emulators, as I don’t have a real monitor for my old C64, but I understand 6502/6510 assembly without problems.

I’m trying to run this program you list. I can write it in the VICE monitor, but I’m afraid I just obtain the typical blue Run/Stop+Restore screen (and a totally black screen if I use CCS64). Only if I run it step by step, I manage to obtain the top black bar with the immediately below white thin bar. But then the program exits.

Are you sure this program works? Does it have to show all these horizontal colour bars with that logo in the middle? What am I doing wrong? I would appreciate your help, thanks.
