Thanks for creating this. I used to do this thing on my HP48 where I would switch between two GROBs rapidly and the slow screen would give me white, gray, and black. Any of the chip8 emulators support that? https://github.com/JohnEarnest/Octo/blob/gh-pages/docs/XO-ChipSpecification.md#bitplanes https://github.com/JohnEarnest/Octo/blob/gh-pages/docs/XO-Ch...

To my knowledge, a handful of emulators have attempted to recreate the HP-48's slow display, but I'm not aware of any surviving CHIP8/SCHIP programs that try to take advantage of this behavior to produce grayscale. XO-CHIP bitplanes are indeed somewhat similar to alternating framebuffers, as you describe, from a programming standpoint.
