[stella] to overscan or not to overscan?

[p.cavina@xxxxxxxxxxxxx (Piero Cavina)]

According to the Stella programmer's guide, a NTSC TV frame generated by
the 2600 consists of 3 VSYNC lines, 37 VBLANK lines, 192 TV picture lines
and 30 "overscan" lines.

The question is: do we really need to do the "overscan" lines?

I'm writing my first game for the 2600 and I didn't care about overscan (I
just draw more empty TV picture lines). After a lot of try-and-miss I could
get a steady picture, so I don't think it's really needed. What do you
think?

Ciao,
