With this Cheat, I will tell you how to quickly switch between spell Books with the press off a button. First, you must have a Spell Book equipped. Now, press Up on the D-Pad and then press R or L. R will equip the Next spell Book while L equips the Previous Spell Book. The best part about this is the face that you don't have to access the Menu, making battles faster and easier.
After you beat Maxim(real) in any castle and unlocked Boss Rush Mode, when you see the Konami Logo at the beginning, hurry and hit up,up,down,down,left,right,left,right,B,A,Start. If you do this right, the sky at the title should be blue instead of magenta. Go to Boss Rush Mode on any difficulty and you are now Simon Belmont.
Simon Belmont Pros-Higher Attack Simon Belmont Cons-Less Distance, Fewer subweapons, slower, can't slide.
Anyways, you'll like him. If you beat Boss Rush on hard with Simon, at the title screen the castle will fade in a few seconds and say Simon "Belmondo" Forever. Enjoy. Also he's bout level 80. Juste is bout level 55.
