Hello HG, When castling short, the king can go on top of the rook, but it should not. As Greg says this is not fast casting just different options. There are 2 options for castling short with the rook, 2 options for castling long with the rook (2 or 3 spaces for both), 2 options for castling short with the cannon and 2 options for castling long with the cannon (3 or 4 spaces each). Here are the rules as I conceived them:
In this game there are 4 different castling moves for each side of the king.
1. Long Rook Castling- King slides 3 squares on the bottom rank and the rook jumps imideatly on the other side of the king
2. Short Rook Castling- King slides 2 squares on the bottom rank and the rook jumps imideatly on the other side of the king
3. Long Cannon Castling- King slides 4 squares on the bottom rank and the cannon jumps imideatly on the other side of the king
4. Short Cannon Castling- King Slides 3 sqaures on the bottom rank and the cannon jumps imideatly on the other side of the king.
The usual castling restrictions apply.
So cannon castling is not possible until the rook is out of the way.
