There is an interesting cheat for Shatterhand.
You can test your fighting skills against the skills of any level boss by entering a two-button code. When the title screen appears, press the A and B buttons in the following order: A, A, A, A, B, B, B, B, A, B, A, B, A, B, A, B. The code will call up the Test Mode with a list of the six bosses (except Grover) and entries for testing background music and sound effects. Move the cursor to the desired entry and press the Start button. By choosing one of the Boss entries, you'll warp directly to the selected enemy's hideout. Remember, only input the code after the opening intro of the game or you could skip it and then input the code there.
