Hi, I downloaded Mupen64 earlier today, and ran Zelda: Ocarina of Time on it, quite successfully. Later on I came back to play some more, and instead of starting fine, it displayed the spinning N64 logo very slowly, instead of at the original fast speed. It runs really slow, and I tried deleting Mupen and extracting it again, but that didn't work. I'm using Ubuntu Linux 6.10. I had a similar problem on my old Windows ME laptop a few years ago, except with Project64.
