Even in that day and age isn't a 256x256 grid a little bit coarse? I know it draws smooth vectors between those points, so it isn't a jaggy problem. But there aren't many points to fit objects in.
- DerekL 11y agoBack then, that was pretty good. The best resolution of any other video game console was 320 by 192. NTSC can't show much more detail than that when using an RF or composite input. Higher resolutions didn't appear until the PC Engine/TurboGrafx-16 in 1987 and the Super Famicom/SNES in 1990.
- boomlinde 11y agoIn this case, the 8 bit DAC doesn't imply a fixed 256x256 "grid resolution", but the "velocity" (which I am not sure is a completely valid name for it either). The beam moves relative to its last position, and the overall magnitude of its movement depends on a different register value.
