Mega Man

Bug: This glitch has been fixed in later versions of the game, but still works in the original NES version. When fighting the Yellow Devil, select your Elecbeam and fire it at the enemy's eye. As soon as you fire, start rapidly mashing the Select button over and over again as fast as you can till it hits. If done fast enough, the beam will instantly kill Yellow Devil in one hit.

Bug: If you switch to the MagnetBeam or SuperArm while fighting the Copy MegaMan, the copy MegaMan will stop attacking. He will only just jump around when you hit the attack button.

Trivia: This is the only game of the original series to have 6 MasterBots as level bosses. In the second game it was made 8 MasterBots which became the series standard. But only 6 in the first game.

Trivia: During the time this game was in development, there was a large push for "Westernization" of Japanese game box arts. The cuteness of the character was thought not to be attractive to the eyes of the US public. That is also the reason for changing Rock to Mega, and Rockman to MegaMan. However, the designer of the was asked to make the box art for the US version of the game with little to no time before the game was actually released and never got to see any source material or the game. So he made a cover that had almost nothing to do with the game. The cover to this game is also rated one of the worst box art covers in video game history.

Trivia: In the following games, replaying a level and getting to the boss room just shows an animation of MegaMan warping away and the level ends. But MegaMan 1 is the only game where replaying a level, you have to fight the MasterBot boss all over again.
