It's my understanding that not all games use exactly
262 scanlines. I think that's just Atari's
recommended number. I think some even use upwards of
280 or so per frame. Evidently these games still run
fine on NTSC television sets.
My question, then, is whether these 'non-262' games
run at a lower screen refresh rate than 60Hz (I guess
they'd have to), and if so, does *this* cause any
potential TV problems?
