Rejoice, as I've written a writeup on how exactly Emulator Examination breaks your emulators: https://codeberg.org/PoroCYon/emulator-examination/wiki/Home
I feel like a diagram might be needed to explain the "eye test" effect better? But also it's past 3 AM here so if people want it, I'll do it tomorrow.

@pcy@icosahedron.website lol jesus. Specifics are hard but I guess the gist is if you swap background mode mid scanline the PPU in some cases uses wrong tile data due to a prefetch… happening? not happening? and the exact behavior is very timing dependent and also slightly weird?
