The Konami Code (コナミコマンド, Konami Komando^?, lit. "Konami Command") is a special combination of buttons that appears in several Konami games. It was widely popularized due to its inclusion in the NES home version of Contra (1988), where it allowed the player to obtain 30 free lives. Since then the code has become part of popular culture in general, even appearing in many non-Konami games and diverse media, such as clothing, advertisements and non-gaming related software.

History

The code was first used in the 1986 release of Gradius for the Nintendo Entertainment System but was popularized among North American players in the NES version of Contra, for which it was also dubbed both the "Contra Code" and "30 Lives Code", because of its nearly necessary use in the game.

The Konami Code was created by Kazuhisa Hashimoto, who was developing the home port of the 1985 arcade game Gradius, a horizontal scrolling shooter released on the NES in 1986. Finding the game too difficult to play through during testing, he created a cheat code to give the player a full set of power-ups (normally attained gradually throughout the game). The code was still present in the released version after Hashimoto forgot to remove it. Players discovered and shared the code. The Konami Code was thus included in the series' other sequels and spin-offs.^[1]

Input

The code is usually entered during the title screen before the game demo begins, and the player must press the following sequence of buttons on the game controller to enable the cheat:

Variations

The original version of the cheat code was designed for the NES controller. The exact sequence varies from game to game and has been adapted to fit the button layouts of different video game consoles, mostly the A and B buttons. For example:

• Any code for a PlayStation controller, which uses shapes instead of letters, would use and instead of A and B respectively.
• In mobile phone games by Konami, the buttons are replaced by 5, 7, 3 on the numerical pad, which is the goroawase pronunciation for "Konami": 5 is pronounced go, 7 can be pronounced nana or just na for short, and the kanji for 3, 三, looks very much like the katakana sign for mi, namely ミ. Together, this becomes "go-na-mi".
• The code is usually followed by the press of a final button in order to activate it. This is generally assigned to the START button, but some games may change it for any other, like the SELECT button.
  • Because the cursor ends at the same spot where it initially was before inputting the code, some games drop the press of the final button completely and the code is activated as soon as it is successfully entered, while starting the game at the same time.
• Some variations change some of the buttons pressed, like requiring to press the L and R bumper buttons instead of ← and →, or changing the order of how the final two buttons are pressed (i.e. A, B instead of B, A).

Usage in Konami franchises (alphabetical order)

Boktai

• Boktai: The Sun is in Your Hand (GBA) — In a room in the Abyss, the player will find a sign with the Konami Code (Up, Up, Down, Down, Left, Right, Left, Right, B, A) inscribed on it. Entering the code will reveal a hidden chest containing a Life Fruit.
• Lunar Knights (NDS) — Enter a variation of the Konami Code (Up Up Down Down Left Right Left Right L R L R) while at the Eastern Solar Bank to start the RockMan crossover quest.

Castlevania

• Akumajō Special: Boku Dracula-kun (Family Computer) - Entering the code at the title screen will display a black screen with the text "There's nothing here!" in Japanese. In the unofficial translation hack of the game, this was reworded as "Sorry, that won't work!".
• Castlevania: Bloodlines (Mega Drive/Genesis) - Entering the code at the title screen (a sound will confirm it) enables the selection of the Expert difficulty in the option screen. The code also gives the player the possibility of starting the game with 9 lives if it is entered at the title screen after the music settings in the option screen have been set to BGM 05 and SE 073.
• Castlevania Chronicles (PS) - Entering Up, Up, Down, Down, Left, Right, Left, Right, X, Circle on the title screen will take the player to a hidden options menu that allows them to adjust the "system time" and turn on/off the transparency of the status bar in Original mode. The system time affects small things in the game, like the hands on the clock tower.
• Castlevania: Harmony of Dissonance (GBA) - Entering the code when the Konami logo appears and choose Boss Rush to play as the original Simon Belmont, with the music and animations from the original Castlevania for NES. While significantly harder due to the limited movement of Simon Belmont, the player can do more damage with this character and collect far more hearts to fuel sub-weapon use against the bosses than the other two characters. Simon is also limited to special weapons from the first game: Holy Water, Knife, Axe, and Cross. (Additionally, the Holy Water weapon gives the "static flame" from the original Castlevania, not the moving flame from when Juste uses it.)
• Castlevania: Lords of Shadow (Xbox 360/PS3) - Entering it at the Load Screen of a Level (With Analog Sticks) and you get a Cheat Menu at the Extras Point.

Contra

• Contra (NES) - Entering the code at the title screen gives the player 30 lives. If the two-player option is chosen using the select button before or after entering the code, both players will have 30 lives. In the Japanese version, the 30 lives code can be used alongside a stage select code exclusive to that version.
• Operation C (GB) - Entering the code at the title screen (followed B and A again) will enable the Stage Select mode. Choose the desired stage by pressing select and then press start to begin. This code does not work in the Japanese version (Contra), since the Stage Select screen is a default feature.
• Contra: Shattered Soldier (PS2) - At the title screen, pressing Up, Up, Down, Down, L1, R1, L2, R2, L3, R3 on the second controller gives the player 30 lives upon starting the game.
• Neo Contra (PS2) - Same as Contra: Shattered Soldier
• Contra 4 (NDS) - There are two methods of entering the code that each result in a different outcome:
  1. At the start of a new game on Normal or Hard difficulty, tapping on the touch screen once the mission starts in the same way as the code (Up, Up, Down, Down, Left, Right, Left, Right) then hitting B, A, followed by tapping on the center of the screen before landing in the water gives the player extra lives upon starting the game.^[1]
  2. Entering the code during gameplay in the pause menu will power-up whatever weapons the player is currently carrying. The code can only be entered once per stage, as inputting it a second time will kill off the player, taking away a life. This code has no effect on the Easy setting, where all the weapons picked by the player are upgraded by default. The code also works on the unlockable emulated version of the NES Contra included with the game, with the A and B buttons being assigned to B and Y respectively.

Dance Dance Revolution

The Konami Code has been referenced in routines for some songs on Konami's Dance Dance Revolution series, and has also been an unlock mechanism on some versions:

• Dance Dance Revolution 2ndMix (Arcade, PS1) - The Single steps on Basic difficulty for the song "Make A Jam!" include the directional portion of the code (i.e. without B or A) five times throughout the song. A faint chime is heard in the music after each such pattern. The song was also a remix of a jingle played behind the "walking" Konami logo animation contained in some older games.

• Dance Dance Revolution 5thMix (PS1) - The last 5 pictures in the Gallery are unlocked by highlighting #224 and entering the code, replacing B and A with X and O, respectively. (This is because the X and O buttons are on the same locations on the PSX controller as the B and A buttons are on the SNES controller.)
• Dance Dance Revolution Extreme (Arcade, PS2) - All charts for the song Twinbee ~Generation X~ contain the directional portion of the Konami Code as part of their charts, and the doubles charts all contain the sequence on the left pad, a reference to the code traditionally being entered by player 1.
• Dance Dance Revolution Ultramix (Xbox) - If a gamepad is plugged in to the fourth controller port, and the code is entered during the credits, all of the game's hidden songs will be instantly unlocked.

The first pattern is ↑ ↑ ↓ ↓ ← → ← → which is the Konami Code without the ending "B, A" sequence.
• Ganbare Goemon: Sarawareta Ebisumaru! (GB) — After having a Game Over, the screen then switchs to the Continue Screen. Inputing the Konami Code (↑ ↑ ↓ ↓ ← → ← → B A) here, gives the player access to the Sound Test Mode where he can listen to all the musics of the game.
