Extended Ending Theme
For some reason, roughly half of the ending theme to this game is unheard during normal play. However, you can hear the remainder on a loop provided you hold Up+A on Controller 2 as Mega Man walks across the screen during the ending.
This is because of the animation freeze code that this button combination activates during levels, which also explains why Mega Man will have a weird animation as he walks when you hold these buttons. Note that you have to hold Up+A for the entire time you wish to listen to the ending theme: if you let go at all (and Mega Man is at the point where the screen normally scrolls up), then the game will continue the ending and credits as normal.

Glitches
Get Rush Jet Early
Normally, to obtain the Rush Jet, you must get it by defeating Needle Man. Instead you can go to Shadow Man's stage and defeat him so that you acquire the Shadow Blade from him. Then, go to any other level and find a weapon energy refill capsule. Don't pick it up yet. Instead, open up the pause menu and highlight the Shadow Blades. Then press Right on the D-Pad, then press start to unpause the game and you should now have an empty weapon energy meter. Grab the weapon energy capsule and you will now fill up the empty energy meter. This energy meter is the Rush Jet. You can now summon the Rush Jet anytime.Get Rush Marine Early
In order for this trick to work, you must have Spark Shooter (SparkMan's weapon), but must not have defeated ShadowMan, the Robot Master who gives it to you. Go into the menu and point to Spark Shooter. While the cursor is on Spark Shooter, press right on the D-Pad. Rush's picture will appear instead of Spark Shooter's picture. Select this, and you will now have Rush Marine with an empty meter. Now, go pick up a weapon capsule or weapon pellet to fill the empty meter with. Once it has a little bit of energy, the Rush Marine option will now permanently appear on your weapons list, even when you deselect it.

Secrets
Freeze Enemies - US/JP Versions Only
On Controller 2, hold Up and A and most enemies will be frozen, making them easy to hit. Some enemies - for example, bosses - will not be affected.Infinite Energy Tanks.
Anytime you find an energy tank in a stage, take it and get a game over. You keep your energy tanks by default after you get a game over, and the energy tank you found will respawn. Rinse and repeat until you have as many energy tanks as you want. Time-consuming, but it will make many boss fights much easier.Music Remix PS
When you are at the mode select screen, highlight the navi mode. Press and hold the select button, the press the start button. Now most of the music in the game will be redone versions of the originals.Super Jump and Invincibility - US/JP Versions Only
When holding Right on Controller 2, you will jump twice as high as normal, and will also be able to survive falling down into bottomless pits. The invulnerability aspect comes in if you fall into a pit when you hold Right on Controller 2, and then manage to exit the pit: so long as you never gather any more health in the level, you will never be harmed, but you also lose use of your Mega Buster. (Boss-earned weapons still work.)
