message: "A 'ball' - a line that is the same color as the playfield. It can be one, two, four, or eight pixels wide."
If the ball is the same color as the playfield, then how can the ball be seen?  Isn't this an error? —Preceding unsigned comment added by 71.242.117.28 (talk) 2007-08-27T05:11:57
* I'm no expert, but I'd guess that the "ball" exists for the purpose of hardware detection of collisions, even though it is not rendered. --Bisqwit (talk) 11:44, 27 November 2007 (UTC)

message: I wonder about the factuality about the NTSC and PAL palettes shown on this page.
When I was a child, I played Missile Command on the Atari 2600, with a PAL system (seeing as I live in Finland which uses PAL), and I distinctly remember that it used the yellow color (#FFFF00): It is this game from where I learned how the TV screen composes the yellow color. Yet, the PAL palette shown on this page shows that the yellow color is impossible in PAL. Where does the error come from? --Bisqwit (talk) 11:38, 27 November 2007 (UTC)

message: This part should either be removed or modified in that this is not the case with TIA where there is no framebuffer. The horizontal resolution is also stated wrong (horizontal resolution depends on the particular graphics object, 1 color clock cycle at minimum of which there are 160 visible per scanline). The given reference -which I presume is "Racing the Beam"- doesn't confirm it, either. Actually, It's required that the programmer compose the image by modifying register values in TIA (of which there are only 5; P0, P1, M0, M1, B) on the fly per raster line. Respectively, Playfield is a 20-bits wide register (two and a half bytes) which can be reflected symmetrically (or not, with tricks) so as to expand it to 40 bits wide. Player objects are 8-bits wide, and can be cloned up to 3 copies per each with 15 pixels of fine tuning (-7, +8) for horizontal coordinate. They should also be positioned on the fly during the scan line. Missile graphics are 1-bit values which are either on or off. The above paragraph reflects more of the later 8-bit home computer video chips like VIC-II of C64.Neurosys (talk) 10:25, 15 February 2011 (UTC)

thread_title: File:Pressure Cooker - Sprites Big.PNG Nominated for speedy Deletion

message: It isn't really 15 colours. It's just the usual 4, but alternated on odd / even lines of the screen. So not even blended, really. Just stripes. I would, if you threatened my family's life, grudgingly admit it's kinda cute, but it's in no way revolutionary. It's just stripes. Nothing apart from vertical stripes, and the effect doesn't work well on most of them. So I'm gonna remove the link, since it's not helpful and doesn't illustrate any features of the 2600 or TIA. 188.29.164.104 (talk) 02:00, 23 March 2014 (UTC)
