Great improvement. Shadow of the Beast still has some minor graphical glitches, it's a short flash of the screen now and then and some moving in the colours of the horizon.
On the other side, S.T.U.N. Runner, one of the most hardware demanding games runs with 60 FPS at 430 MHz, so no problem with the speed I think.
The screen doesn't seem to fit 100% on the screen, the life bar in Shadow of the Beast is missing some lines.
But apart from these small things very good and stable as far as I see.
