Castlevania Adventure Cheats for Game Boy

Secret Room in Stage 3
At the end of stage three, you climb a long rope on the left of the screen with a thick wall to the right of you, this is right before the sub-boss at the end of the level. When you are about half way up that long rope you should be able to jump into the wall and walk to the right towards a variety of power-ups.


Secret Room in Stage 1
In the very first stage of this game, there is a hidden room. In the first stage, you must climb ropes to get through the level. The second to last rope, on the right-hand side of the screen, leads to a platform with a tree stump and 2 graves with crosses visible. If you climb up this rope above where it appears to end at a brick wall, you will climb into a hidden room with four power-ups.


Secret Room in Stage 2
In the second part of the stage, where you have to choose between ropes, go right, then go left. You should be in a room where you go down stairs, and giant eyeballs are speeding toward you. Kill an eyeball while its on the middle step. Once done, a hole will open up. Climb down it for power-ups.


Extra Life
In the first level, do not whip the first ten candles. When you come the 11th candle, whip it to reveal a 1-Up.


Secret Room in Stage 4
In the room where there is only a guy with a boomerang. Kill him and climb on the rope to the right (but dont exit the room). When you are high enough, jump left into the air and watch our hero standing still in the air! Or, on an invisible platform. Move a little until you are in the center of the screen and jump. Youll grab a rope (also invisible) which leads you up in the bonus-room of the 4th stage.
