Konami code or read between the lines

Konami Code History

Back in 1986, Japanese company Konami , one of the leading developers and publishers of video games, programmed the secret key combination in the version of the game Gradius for the NES game console.







However, this combination of keys has gained real popularity thanks to the American version of the game Contra (as the “code for 30 lives”).

')





In different games, this code has a different purpose:

• Increase the number of attempts
• Full armament at the beginning of the game
• Adding lives
• Other

Konami code

The Konami code itself consists of a 10-digit combination:

Konami code on the web

Using Konami code is also common on the web . Many website developers use it to hide some information. However, this is mainly “just for fun” .



Some examples of using Konami code in the web :

• For example, on the Digg website, as you enter a combination (↑ ↑ ↓ ↓ ← → ← → BA), the photos of all the blocks are changed to others.
• On the Geek & Hype website, a secret combination leads to the reproduction of the cartoon All Your Base Are Belong To Us
• Play the game "Batman v Superman" by entering the Konami code on the ProfiTheme website
  
  
  
  
  
  
• But on the rainbow service of Cornify, you can draw all the colors of the rainbow right in the margins of the site, provided that after entering the Konami code, add Enter, enter, enter
• Site Log will remind you of the origins of con code .
• Play the famous snake on the ElliottKember website .

An example of a script implementation for embedding a Konami code call into the web is as follows:

this.startWaitingCode = function () { var keyChain = '38384040373937396665'; /**        */ currentKeyChain = '', /**     */ self = this; $(window).on('keydown.konamiCodeKeys', function(event){ currentKeyChain += event.keyCode.toString(); /**      */ if(currentKeyChain.match(keyChain)){ /**       */ self.init(); $(window).off('keydown.konamiCodeKeys'); return; } if(currentKeyChain.length > 20) /**       */ currentKeyChain = currentKeyChain.substr( -20 ); }); } 

There is also a mass of resources that have hidden encrypted features in their source code. For example, the KonamiCodeSites resource is a list of such resources, which must also be called up using Konami code itself. So to say, examples in the example.
