some news straight from StrmnNrmn's blog
There will be sound support, but I think speed and compatibility are more important at the moment (any audio will sound horrible until the emulator is running at close to full speed).
Save is definitely a big priority. It shouldn't be too hard to get working, but again I don't think it's a priority until some of the compatibility and performance issues are addressed. A better GUI is definitely required too (if just to allow the controller to be reconfigured on a rom by rom basis)
