Mega Man 4 is a platforming game for the Nintendo Entertainment System.

The game starts with the backstory of the original game as well as this one, which is a nice touch since Mega Man 1 had no such opening story sequence. Just like before, our hero must defeat eight robots, along with the mad scientist who created them...only this time it's apparently a different mad scientist!

As always, when you beat a Robot Master, you gain its weapon. Each Master is weak against one of the others' weapons. Additions from the previous entries are back, like energy tanks, Rush the robo-dog, and the ability to slide.

A welcome new feature is the ability to charge your main weapon, which gives you a slight edge if you haven't yet obtained a particular boss's weakness. There are two new support items: the balloon and the wire. The balloon lets you create floating platforms to jump onto (just like Item 1 in Mega Man 2) and the wire latches onto the ceiling and pulls you upward. They seem a little unnecessary since Rush is still present, but they give you more options to tackle any situation.

A password system is an added feature and lets you continue after defeating the 8 Robot Masters.

This is a bug fix or improvement patch made by Puresabe for Rockman 4, although it seems to work in Megaman USA roms too. It enables you to jump while sliding underwater or near ladders.
