I'm a huge KI fan, but my 1.6GHz P4 wasn't cutting it with MAME and for some reason, U64 would always crash and shut down on my machine.
Now I've got a dual P4 (3 Ghz) with 1 gig of RAM and a PNY GeForce 6800 video card... it runs better, but with a lot of audio stuttering (MAME v104). I was under the impression that people were running it perfectly in MAME, but that might have been wishful thinking. What emu are all the KI fans running this game under?
Is it better to focus my efforts in getting U64 to work? (I might have better luck on my newer machine).
I'll also try getting the latest Direct X version.. maybe that'll help a little.
