Sony moved *part* of the PS2 hardware to software emulation, specifically the Emotion Engine. The Graphics Synthesizer (GPU from the PS2) hardware was still left in. This latest version removes both the Emotion Engine and the Graphics Synthesizer.
So either the PS2's GPU is either too difficult to do in software or too costly
