I have some problems.

1. Doesn't sound emulation work? Or is it just me? =)
2. I tried to play "Cedric and the lost sceptre", and it works just perfect until the new game/enter code screen, where I can't choose anything because neither keyboard nor mouse seem to do anything. Do I have to tell the program somewhere that the keyboard is supposed to work as my joystick, or something?
3. I tried to play "Beneath a steel sky", and it works just perfect, except moving the mouse is a bit strange (I did notice that this was listed as a bug that's being fixed) and the speed is a bit too high. Again, is this something I can configure somehow?
4. In general, a documentation wouldn't hurt =)
