After a bit of a small, somewhat unintended break, the next video is finally out. I have always been curious how vector-based arcade games worked, since I'm so used to the raster-based graphics pipeline and all. So this video was fun to work on since I was able to learn all of this myself too! Hope you enjoy.

Editor's commentary for this video will be on Thursday at 4pm eastern time! I might also do commentary for the SMB2 Eyes video too, since I completely forgot to do that last time, whoops!

Super interesting! The way calls/returns work reminds me of Vulkan's secondary command buffers, or OpenGL's much-maligned display lists. Everything old is new again :). I did notice a small error at 3:31-ish - the first vector in the list is "(472, 542) (540, 542)" but should be "(472, 542), (504, 542)".

Ah, nice catch! Thankfully not a terrible error, so I'll just leave it be (rerendering and splicing in a fix takes way more effort than it should, heh).

Awesome video! It's really interesting to see the inner workings of the vector display tech in action. :) Just curious: Have you looked into how the Quadrascan compares to the vector hardware used in the Vectrex and for other arcade games, like those from Sega and Cinematronics? Vectrex is particularly interesting to me. I had one as a kid. I remember how it did text - small raster sweep to display numbers and letters, and in one game, a pinball. Pretty neat.
