man i hate imageshack. you can just upload your pics to emuforums, by the way.
anywho...try using Eternal for sound. if you're using save states, don't. if you save state without sound, whenever you load it, there won't be sound.
you can also use Run ISO, which doesn't use the CD plugin. i don't know if there is a performance difference or not, but it's handy if you play a lot of different ISOs.
