Mega Man 2 (USA) ROM

Mega Man 2 is the second installment in the original Mega Man series (before all the spin-offs). Capcom added and improved many things over its predecessor, like adding two completely new robot masters, removing the point system and giving players a choice of two sifficulty levels.
Many of the newer Mega Man games (especially the ones from the original series) take some elements from Mega Man 2. It's also renowned for its music, apparently some of, if not the best in the series.

 
Mega Man returns to fight evil Dr. Wily in Mega Man 2, the hit sequel to the original game. In Mega Man 2, Mega Man is now going up against Dr. Wily's 8 brand new robot masters who intend to take over the world for their malicious master! It will take everything Mega Man has in his arsenal (including the arsenal of his enemies), to save the world from the clutches of this mad man.
With helpful items provided to Mega Man by the noble Dr. Light, and weapon upgrades from the 8 robot masters, Mega Man is packing heat, and looking to take names! THIS is the definitive game of the series, with classic robots enemies, and a remarkable soundtrack everyone has come to admire.
 

One of the best if not the best game from the 80's. Megaman 2 brings back a lovely nostalgic feeling. It was awesome!
