Things still to do in CD-ice

Propper Windows GUI.

Sound support (only CD-i system calls are emulated at the moment, sound is not output).

Some screen handling (transparency/mixing, Masks, various "screen off" command combinations).

Joystick/Mouse support (only using keyboard at the moment for 1 player emulation).

More system functions/functionality for better compatibility.

DV support  for DV only games and DV movie CDs.

Integrated debugger/system watcher (there is a debugger in there, but YOU can't access it) ;)

Propper CD-i frontend, just like your CD-i (play audio CDs, examine NVRam etc).

Get Linux version up to level of windows version.

Lots of other stuff :)
