well i decided to be spontaneous and upgrade via the diff (thinking we're using
the same ver now). anyway i find with -ad sun it only outputs anything for about
3 seconds (meaning i have to open a rom fast or i will not hear anything at
all). -ad sdl gives same results as previous 1.42 build. setting to 48000 still
has static, though i did notice the 'waves' seemed to get closer together and
it did seem a big clearer..

yes actually, this is the part where i was meaning to mention to you when you
originally made the sdl patch etc. the sound in zsnes was good enough that it
actually had next to no static (a little bit here and there but seemed random)
however, the games seem smoother now, as if before the audio was holding it
up. still a step in the right direction, no?
