With the above code on, enter any town map and pause the game. The menu doesn't draw correctly if there is geometry in the background so it is advised to use the levitate code below, get far into the sky then pause the game. To move in this menu press Up / Down on the analog stick then press A button over your selection.

Hold R to levitate:

Regional Differences

Title Screen

The North American and European title logos are completely different from each other. Europe's design is somewhat closer to the original Japanese, as seen below.

Other Differences

  • The opening theme and Impact song are removed in international releases of the game.
  • The Japanese version allows saving to the on cart SRAM battery or the controller pak. Konami removed the cartridge save feature with several other N64 games when they were exported overseas. Castlevania 64 (and its sequel) saved by using 4k EEPROM.
  • Ebisumaru's Z-button charge attack was completely changed for International releases. In Japanese versions he would perform the "Onarabomu" (Fart bomb). Internationally, he uses "Poison Mist". This involves different animations, see a comparison below:
