Octojam 7: The CHIP-8 game jam

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?

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.
