For some reason, people still remember the famous Konami Code, even though many kids played the game without knowing the secret. The reason for this is because the Konami Code is considered one of the greatest games ever made. If you played Contra on Nintendo Entertainment System, you might know the code by heart, and you'd probably tell everyone about it.
. Konami released a sequel that was supposed to give you more lives than the original one, but the Konami code remained as the cheat's key. To this day, gamers have been trying to figure out the Konami code to unlock secret levels and get that extra life every time they start a new game. The code became popular among Video game cheats gamers as people found ways to use it on different games. This eventually led to the creation of the Konami Code. The most common ways to unlock the codes on newer games are to go to the main menu and press B-A-D-F-G, or go to the options menu and press A-B-X-Y-Z. There are others, but those are the most common ones.
If you want to beat the video game on your own, there's no need to play the Konami code or anything like it. You should just play the game according to the rules and not look for hidden codes that can help you win more. Some games, however, do have codes for additional features. These are not the same as the Konami code. If you don't know what these codes are, you shouldn't bother looking for them. You should also avoid any game that asks you to enter codes for additional features or unlockables.
