[citation needed] for that assertion. Atari 2600 is extremely limited in the number of sprites available on-screen at the same time. If you've played Pac-Man then you know that 5 is too many, because all of the so-called "ghosts" are actually flickering. They're doing that not for a spooky effect, but because they can't be simultaneously displayed. That sort of sprite flicker doesn't happen in Pitfall!
- tom_ 4y agoThe sprites can be replicated by adjusting NUSIZn for the player of interest: https://archive.org/details/Atari_2600_TIA_Technical_Manual/page/n19/mode/2up https://archive.org/details/Atari_2600_TIA_Technical_Manual/... Looks like the tree branches could be two copies on the left, then two more on the right. Not much going on in that region so plenty of time. EDIT: presumably this bit: https://github.com/johnidm/asm-atari-2600/blob/8b613f3c4bc80d2dfec2c270395b0a97c992c9af/pitfall.asm#L484 https://github.com/johnidm/asm-atari-2600/blob/8b613f3c4bc80...
- corysama 4y agoYes, but the limitation is per-scanline, not per frame. Thus, “racing the beam”. The tree branches are above all the other sprites besides the swinging vine.
