Konami Collector's Series: Castlevania & Contra

An official emulator on a disc that features five NES games from the two big Konami franchises that start with the letter "C". It was soon discovered that the game contained somewhat altered NES ROMs of the Castlevania and Contra games, mostly to remove references to Nintendo. The ROMs themselves were released after the discovery was posted on a message board in December 2002, and they've been available on the internet since then.

Nearly eighteen years later, the compilation was rereleased on GOG with the DRM removed.

Jackal#

Despite having no real connection to either Castlevania or Contra aside from being made by Konami, Jackal is a hidden game in the collection.

Originally thought to have been unused, Jackal can be accessed by hovering over games and pressing the B button (defaulting to "A" on the keyboard) in the following order: Castlevania III, Castlevania II, Contra, Castlevania, Super C, and Castlevania III.

Once this is done, the menu will fade out, and Jackal will start up.
