Note however that certain older Linux versions have a bug in their threading which would cause all libao drivers to not output sound.If you're having such an issue, install a new Kernel.
I would like to thank all those who reported bugs and sent in patches for v1.50, we've fixed roughly 3 dozen problems that cropped up with v1.50, including issues with loading older save states and various save state saving/loading problems, so this release should now be quite stable.
See zsnes --help for a list of drivers you can use.
Feel free to play with each one and see which works best for you, there should be something to make everyone happy.
You're now also able to dump past the end of a ZMV.
And saving the best for last, there is now a custom multipass lossy dump option with decent default settings so you can dump really tiny good quality AVIs of your runs (and tweak dumping settings to your heart's content in zmovie.cfg).
