about sound problem, I solved using these settings, open->Sound Settings:
Sample rate: 44100Khz
Buffer size: 150msec
Fragment size: Very Large
Speed Adjustment: Flexible
Volume: 100
Sound Output mode: Stereo
I also changed the "VICII Video Setting" setting the "Render filter settings" to: "none"
Tested the joystick with differents games no problems... I have, instead, problems with disk image (d64).. For some reason everytime I attach (with autostart option) an image, it reset the warp mode and for some reason then it cannot load any programs..
