In counting up the stuff it seems possible. No more than six distinct objects (allowing for sprite doubling) seem to appear on any scanline. Notice how the starfield is absent in the busiest (six object) scanlines, indicating it is being used by one of the other objects in that portion of the screen. But I'm having a hard time imagining any way to draw all that with any time to "think". It might be "legit" in the sense of being a 2600 image, but I'd guess it had to be a straight static image where the contents of the graphics registers are being read during the busy section straight out of ROM, without any conditionals and/or indexed-indirect stuff happening... In that case Supercharger RAM could make it a reality ;) > If it employed flicker, maybe, but otherwise no. > Also, the rainbowing in the meters seem to use colors outside of the > 2600's palette but it's hard to tell for sure. > > I'm fairly certain that, like Doom, this image was created with an Atari > 8-bit. Though I can't pin down anything that couldn't be produced as a static image on the 2600, you're probably right. -- mor@xxxxxxx http://www.crl.com/~mor/ -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/stella.html Don't post pirate BINs to Stellalist.
