GCDual is an internal hardware designed to run GC-Video by Ingo Korb for the DOL-001 Nintendo Gamecube. It outputs analog video and HDMI simultaneously. It can output 240p/480i/480p in all video modes. 240p/480i and can be line doubled to display 480p. The analog portion supports the following outputs: RGBS/RGBHV/RGsB/YPbPr. Composite sync can output TTL or annenunted levels depending on the jumper state of JP2. RGBS Scart cables can easily be setup to use a CSYNC cable or Compsite Video Sync cable.
There currently is no good "off the shelf" solution for VGA. For YPbPr I designed an adapter to allow you to use a Wii component cable. This adpater is open source and can be built with these files:
