CancelDirectionCode enum inside Cancel objects.
If 15th bit is not set, it means it's a direction code of an input. If 15th bit is set, depending on the value of the variable, it indicates the end of the cancel list, or a pointer to a group cancel list.
If it's a pointer to a group cancel list, the index of the cancel in the group cancel list is in the move_id member in the Cancel object.
