I have been reading recently that there is a version of the Nintendo Gamecube that was exclusive to Japan called the Panasonic Q.
What are the exact differences between the Japan exclusive Panasonic Q and the NTSC-U/PAL version of the Gamecube?
Panasonic Q was just a GameCube with a built in DVD player, which original GameCube lacked.
The Panasonic Q (also known as Q and GameQ) is a hybrid version of the GameCube with a DVD player manufactured by Panasonic in cooperation with Nintendo. The system was officially released only in Japan. A feature of its main competitors Xbox and PlayStation 2, the GameCube lacked commercial DVD movie playback functionality due to the use of the Nintendo optical discs format for games and the correspondingly small disc tray.
