  • There currently is no good "off the shelf" solution for VGA. 
  • For YPbPr you will need a standard Wii Component Cable.
  • If using a standard RGBS/Scart cable, it will need to be modifed to work the WiiDual.  The Color channels need to be swapped and Composite Video needs to be remove from the console.  These are both simple procedures. Please look at this image for details on how a modified RGC cable should look: https://i.imgur.com/nwVKO9r.jpg

Retro-Access has a cable that requires no modifications.  It will also allow CSYNC over the DTerminal lines.  This will allow for Composite Video to remain intact.  This will be the recommended cable.
