My bugfix version has just a few minor ui bugfixes, plus it saves the ini file in your fba executable directory, which can be handy - instead of on c:\ (I think, its been a while).
I found out that a direct connection is the best way to go, not wifi. For example: cable modem/adsl -> router -> PC, not cablemodem/adsl -> router -> wifi -> pc.
8 Audio buffers seems to be good, and 44100 hz. make sure BOTH sides uses the same audio buffers & hz. also, make sure both sides have the same plugin and interpolation settings for samples and FM.
Under video, make sure both sides have "Force 60hz" OFF. I think auto frameskip OFF is good, too.
P.s. Ninja Baseball BatMan is a good game to play via netplay
