I just made two presets for Motorotor. One goes by the rule that the board rotates at the end of each move, and the other simulates the rule that the board rotates at the beginning of each turn. In trying out your sample game with both presets, I learned that it is illegal no matter whether the rule is to rotate before the move or after the move. When you rotate before the move, f10 does not exist when it is Black's first turn to move. When you rotate after the move, there is no piece on c4 for White to move on his second turn. It could be that in your sample game, you sometimes rotated the board before the move and sometimes rotated it after. But your sample game never indicated when the board was rotated during each player's turn. So it would provide incomplete information for anyone wishing to follow it. If this is not what happened, then some moves have been recorded inaccurately.
