Castlevania is an action platformer for the Nintendo Entertainment System. Known in Japan as Akumajou Dracula ("Demon Castle Dracula"), this game is about a clan of vampire hunters known as the Belmonts hunting down and killing Dracula himself.

You play as Simon Belmont, and fight your way through Dracula's castle (known in English as "Castlevania", a portmanteau of Castle and Transylvania, har har). You have many weapons at your disposal. Your main weapon, the Vampire Killer whip has somehow been passed down through the Belmont clan for generations. You can get power ups for that (essentially changing it from a leather whip, to a short chain, and longer chain whip). You also have many sub-weapons, which require hearts to use. These include a knife, throwing axe, holy water, cross boomerang and stopwatch (which freezes all enemies on screen). You can only throw one of these in a certain period of time, unless you get the "II" and "III" powerups.

V1.4b: the ZIP file now contains a patch for the USA version of the game
+ minor corrections, new (and better?) fight against Drac 2nd form.

V1.3: minor corrections, better fight against mummies!

"Prince of Darkness" is a big evolution of my previous hack "Horror of Dracula". The biggest change is the modification of enemies behaviors.

Here the list:
- Level 1: black panther, vampire bat boss
- Level 2: spear armor, medusa boss
- Level 3: mummy (you MUST fight my mummies!)
- Level 4: fishman, Frankenstein's créature
- Level 5: blue skeleton, axe armor (beware your legs!)
- Level 6: blue skeleton (different/L5), Dracula 2nd form
