Yeah, old news. When I tried it when it came out it was slower than both MAME and ZiNc themselves on my machine. I think I'll stay with arcade quality graphics at ~40fps than 'enhanced' graphics at 20fps!
On a side note, I dragged out the old ZiNc again to see if it still ran, ZN-based games and Tekken 3 work fine but for some reason System 11 games do nothing but crash on load without even showing the window or going into full screen. Maybe RB jinxed me over my blind post in the MW programming forum!
