Bad Signal and MC Demo do not look exactly like on my TV card and real machine, since the horizontal synchronization is not stable there, but I assume this depends largely on the monitor, TV, or TV card being used. But both demos depend on the equalization pulses being turned on all the time, and MC Demo takes advantage of the doubled horizontal sync frequency to make every other frame shifted horizontally by a half line. Since the TED emulation in plus4emu 1.2.0 and later generates a full composite sync signal, which is decoded by the TV emulation part, effects like in the above demos, or interlaced display (of which a few examples were posted in another thread) can work. Typing 'poke 65287,72' will also make the picture unstable similarly to a real machine.
I did not write the SID emulation, it uses reSID 0.16, which was originally written by Dag Lem.
