There's a part in the hallway to the left where you fly a little drone into a laboratory to take a picture. It's one of the traditionally hard places to emulate for these sorts of emulation strategies that abstract the graphics output from the memory pathway of the real system. That's because the effect to make it look like a security camera that would happen these days as a post process fragment shader, is instead done on the main CPU, just reading and writing to the framebuffer. So the GPU emulation actually needs to write out the framebuffer at the correct format/resolution. And then you have to read the framebuffer from memory, not short circuited out of the GPU directly like is the core of how this is designed to get it's benefits.
