The Game Courier preset has been posted.  Might I suggest, though, that you use 3 square colors.  This makes the knightrider moves much easier to visualize.  (Use "checker pattern" of "10.21." - this will alternate between the first and third colors for the dark squares.)

Regarding Champion vs. Bishop - on 12x10 the Bishop has a Betza mobility of 5.07 while the Champion is at 6.70.  These are the values when the board is at 30% occupancy - which seems to work well for Chess, but Chess starts out at a board density of 50%.  Wide Nightrider starts with a densite of 40%, so calculating the mobility at 20% may be more appropriate.  This yields 5.80 for the Bishop, the Champion still at 6.70.  The density of pices on the board needs to get down to 8% before the mobility of the Bishop equals that of the Champion, and even then the Bishop is still colorbound.  So I think there is no doubt that the Champion is stronger.
