Copy Protection Code Wheel
When you first load D-Hero, an instruction will appear on screen requesting that you enter either a number or letter from the code wheel which you will find in your D-Hero game package. An image will appear on screen which should recreated using the code wheel by turning the inners section to match the image, and then you should enter the number from the window indicated on the screen. Once you have successfully bypassed the copy protection, the D-Hero Screen will appear.
