TV Swan

The “TV Swan” refers to a set of devices made available by Bandai to display WonderSwan output on a TV.


These general traits seem to be true:

  • TV Swan units support horizontal/vertical screen orientation; this is detected by observing the state of the vertical screen orientation icon to the right-hand side of the LCD.
  • TV Swan units shift the screen when undocumented WSC vertical timing registers are changed, much in the same way as third-party IPS panels (see: Fire Lancer).
