Control-G Does not produce any noise on the 64. There are no sound routines
(except to clear the SID registers at start-up) in the 64 ROMs (I think they
were rushed on putting the 64 to market; later they released Super Expander
and Simon's BASIC which offered sound commands.) I usually use a game
cartridge to check the 64's sound, video and joystick ports. Jumpman Junior
seems to be my favored one (mainly because it does not rely on much of the
KERNAL/BASIC ROMs in it's operation.)
And yes, the Genesis A/V cable is compatible with the 64 (I've used the same
cable on both units).
