I never would have guessed that the Kickstart 1.x graphic was vector, but it’s so clear in retrospect. It’s not hard to spot the nodes of the pre-Bézier shape paths once you’re looking for them!
ROM space was definitely at a premium, similarly the PS1 booting splash screen was a rendered 3d graphic, with synthesized sound, not a static image with PCM data.
