The Pharoah Shot charges above Mega Man's head. However if the ball of energy hits an enemy while you hold the A button, you won't lose any Pharaoh Shot ammo.
First, go to ProtoMan's room in CloudMan's stage (right before the outdoor part before the boss, there will be a ladder. Use Rush to get to it). ProtoMan will comment about using weapons to find areas. Then go to ProtoMan's room in TurboMan's stage (this one is at the very top of the area with the traffic light platforms; go through the wall just before you reach the top of the ladder). He will mention something about the Super Adaptor.
After you go to these two rooms (doesn't matter with order you go to those), go to ShadeMan's stage. Continue like normal until you reach the Pumpkin mini-boss. Shoot the small orange core of the Pumpkin (NOT the eyes on the outside). After you defeat it, it will open a hole on the bottom. Go down until you reach the room with a lone green Sniper Joe. Defeat the Sniper Joe, and instead of going down the ladder, go right through a secret passage and enter the gate you find. If you did everything correctly, ProtoMan will challenge you to a duel.
Once you defeat ProtoMan, he will give you the ProtoShield. This can be used at the same time as the MegaBuster (don't forget to select it), and it will block many enemy shots (like those birds that hatch from the egg; let all of them run into the shield and they will die).
Enter the password screen for any of these games and enter the following password that corresponds to that game. These passwords will give you all weapons and upgrades, or all upgrades and most bosses defeated. (MM=megaman, ex. MM3= Megaman 3 game). There are no codes for Megaman 8

In Mega Man 1, when using a weapon that goes through an enemy --- Rolling Cutter, Thunder Beam, Ice Slasher, or Fire Storm --- press Select (L+R on the Gamecube controller) the second the weapon hits an enemy. After you press Select again to unpause the game, the weapon will hit the enemy a second time. This makes a joke of virtually every robot master battle in the game, so long as you have a weapon that can be used in conjunction with the glitch.
Unfortunately, this was fixed in later versions of Mega Man, and does not work in any other title besides Mega Man 1.
To change the stars usually seen on the screen that introduces bosses in Mega Man 2 into birds, press and hold Start and B immediately after choosing a stage.
