The Knight's Tour 4

I have to wonder if solving a completely insurmountable Professor Layton puzzle by writing a program to work out the solution is considered cheating. They throw the original Knight's Tour problem at you, for goodness' sake - you're going to have to offer a lot more than 99 Picarats for me to work that out unaided.

( Output and solution. Completely safe to look at, you'll never remember it )

Additional challenge: Do it in ZZT.
