So far I only have one thing for PSP hints.
I'm more of a nintendo person, but I
love Castlevania. Here are some hints and cheats:
Castlevania: Tthe Dracula X Chronicles
unlock peak-in normal boss rush mode get the key after defeating shaft, then defeat the next boss in line to unlock peak
unlock rondo of blood-in the 4rth stage, finad a wall that when you destroy it a bomb will appear attack the bomb and the wall will explode, get over to where a
vase is above a boss door break to vase finding the game
unlock symphony of the night-in the secret 3rd stage get up to the 5th room at the very beggining of it get on the top and walk over to where a gravstone is break it and find the game
3rd stage secret room-at the beggining of the stage with a cliff there and a gravestone on it, push the grave stone over and you will fall into a room with
all the secondary weapons one 5 heart, and 1 extra life.
