i just payed 5 mins of shenmue 2 on 1280x1024 at full speed (there was a sound glitch i think though causing a pause or might of been cos it was loading off a cd) looking great with minor minor bugs. The most amazing emulator ive ever seen... Also sonic 2 is running at an average of about 30-40fps while the cpu is overclocked to 145%. Also at 1280x1024 full screen. This has more bugs though causing some gfx errors and also the screen to have a totaly black frame or two every now and then. Overall amazing.
Not bad for emulating a 128-bit console! But it's still early days yet - SNES/MD emulation has been around for 6-8 years now, and even now they still haven't perfected them.
