At the title screen, highlight Geki Mode. Hold down L1, L2, R1, and R2, and then 
press start. If you've done this correctly, the words ''Original BGM Music'' will 
appear. Although the code only triggers when you start Geki Mode, after that it 
will carry over to Easy and Hard Modes.

During Geki, Easy or Hard mode, pressing Select will enable you to get up to 9 
continues. Whenever you use one, you can use this little trick to keep your 
continues at 9.
