This section contains Game Genie codes for Mega Man X, X2, and X3. It has been said that X2 and X3 don't work with the Game Genie, but I have tried almot all of these codes personally, and I can confirm that they do indeed work. I don't know how many people still use Game Genie, especially since the first three games have been out for quite awhile now, but hey, it can be fun...

Mega Man X2

DC2C-046D -- no dots appear when charging

EE2A-070D Messy menu--doesn't seem to affect gameplay

Slowdown--weak in some places, extreme in others
Junk--harmless in some cases, deadly in others
Can't use sword until a couple minutes after sparkles completely disappear
EE60-D401 Sparkles behind level 3-5 shots fly across screen twice
SIDE EFFECT: Can't use sword until a couple minutes after sparkles completely disappear
EE60-D701 No sparkles behind level 3-5 shots

EE60-DF01 sparkles after level 3-5 shots have pretty "shimmering" effect
D586-6F26 Super jump
DB86-6F26 Mega jump
D886-6F26 Ultra mega jump
82CB-0D2F Infinite special weapons (once you have them). Only works if you don't power-up the special weapons.
82CB-0D2F + 82CA-0F2F Infinite special weapons (once you have them). Works even if you power-up the special weapons.
EE29-D7D1 Large life balls instantly fill an entire subtank, although small life balls do not add anything. If you fill two or more in this way, you actually get a bonus tank (for example, if you have 4 tanks, you get 5 charges out of them)
196A-D405 This code is still in development, but it's the best out there for now. Both Zero's and X's lightsaber weapons (level 5) rapid-fire huge energy waves (think of how X's sword normally works, in a long stream, that also works for Zero). It constantly shoots off in the direction that you first used the sword; turning around doesn't move it. The code can be turned on and off at will. In fact, dialogue will not start until you turn the wave off, and you MUST NOT use the wave against Mac or Doppler. On the plus side, it still does 16 damage to any other boss, and X can deactivate the wave simply by choosing a different weapon from the menu (L and R do not work while the wave is firing)..
