Are you joking? That's what those routines are called that create the
illusion of more than 2 players by flickering.

I was thinking you could change the background color from black to purple
(and back again) where it crosses under the playfield. Not a huge quality
loss if it isn't doable though.

Yeah, this is one of those unfortunate times where the game almost, but not
quite, meshes with the hardware. You'd really have to butcher the mazes to
get them to work with player cloning.

I was thinking that missiles would be used for the eyes, and I was also
thinking that you could double-width just the missiles to cover both eyes,
but now that I think more about it I realize that you can't do that. D'oh.

There's a nice wide border for packing extra cycles in. :)

Actually it's two 4.3-chars. Doable? I give 50-50 odds.

If someone ever actually starts this, I'm sure they'll try to include the

I've got any MPG of it. It was recorded from one of the Videogame Expos. I
forget where I downloaded it.

Okay, now pick apart the 2600 Ladybug fake. Yikes!
