Thanks everyone for discussing it, I hope this can be implemented in some way in the near future, even if it's not 100% accurate.
If we get 90% accuracy or less, it's better than nothing. The original Nintendo GameBoy VDP for example, still hasn't been reverse enginereed, so it's still all high level guesses on how the hardware works.
I would love to help with this, but unfortunately it's way out of my technical knowledge and I lack the tools. Still, my best of luck to the team that works on this.
