Super Castlevania IV Cheats
There is an invisible staircase leading to Dracula, and a pit below it, on the level just before Dracula is encountered. Take a large jump into the pit from the edge to land on an invisible platform. Move to the left side to reach a staircase that leads downward. Before going down, move all the way to the left to find some power-ups. Collect 99 hearts, a triple boomerang, and the best whip, then carefully return to the stairs to enter the next level.
Levels 3-1, 6-2, and 9-2 have bonus rooms that contain a large amount of power-ups.
Level 9 treasure chest
Jump 255 times on any treasure chest on level 9 for a power-up.
