Mega Man X3 - Zero Project V4.1 (Base Mod & Source)

Hack of Mega Man X3


Note: The project comes with a separate .txt inside for the new locations of many RAM values used in this project since most of the original Game Genie codes used will no longer work due to vast amounts of location changes. Use this file for various cheating needs.

A large modification of Mega Man X3 that allows Zero to be fully playable. Among this, there are vast improvements over some aspects of the original game along with a plethora of new features such as a Save/Load system. Also, the game has been modified to be ‘FastROM’ as well so some slow down has been reduced, but it’s still prevalent throughout the game.

This version is considered separate from the original Zero Project since this one has such an entirely rewritten system from the ground up and separate features that people may or may not like compared to the prior version.

The project comes with four separate patches:

  • Unheadered for an unheadered ROM
  • Headered for a headered ROM
  • Unheadered with Zero sub-weapon colors (Uses X’s) for an unheadered ROM
  • Headered with Zero sub-weapon colors (Uses X’s) for a headered ROM

This is so all grounds are covered for mistakes on patching minus the wrong ROM.

Let it be known that I do not really like the original X3. I found it kinda dull, padded, and borderline frustrating with certain mechanics taken. However, not only did a dream of a fully playable Zero in X3 become a reality, but many other problems I have are fixed.

1) The obvious one: Zero. It’s the partner mechanic that X7 started. Say what you will about that game, but a legit praise I have for that game is the partner system. Zero is amazing early on, since his buster and saber can deal with the annoying enemies that can make mincemeat out of you early on. And now I don’t have to worry about making one wrong move and have Zero never come back for the rest of the game. He’s balanced fairly to X (higher offense, mobility and max HP in exchange for lower defense, weapon conservation, and a larger hitbox), and he can grab items too! I adore that the Heart Tanks increase both lifebars on X & Zero. Contrast to X5, X6, and X7 where a Heart Tank only increases the one who grabs it, limiting your options. Sharing the Heart Tanks allows for more versatility in gameplay and makes it more fun.

2) Project Zero also pays attention to X as well and refined his armor to be more useful. The biggest change is the Buster upgrade, which no longer spreads its fire and misses almost everything. It now travels in a helix pattern, and hits multiple times (similar to X2’s buster). If you know what you’re doing, you can SHRED away Maverick health bars and destroy bosses in seconds. The Body upgrade no longer emits that annoying flashing shield, and functions almost identically to X1’s Body upgrade. The Head upgrade doubles Special Weapon ammo (similar to X5 and X6). And finally, the Golden Armor is no longer locked out after entering a Chip capsule. So you can take advantage of the Chips and still access the Golden Armor for endgame.

3) Level design has been slightly changed to reduce backtracking. Backtracking was my biggest issue in X3, since there’s so much of it, and it’s very clearly padding. Project Zero trims the fat and fixes multiple issues related to backtracking. For example, the boulders in Tunnel Rhino can still be dropped by the charged Triad Thunder, but the Spinning Blades and the Z Saber can now cut the ropes, eliminating the need to backtrack to that stage at all (since you always have the Z Saber *wink wink*).The biggest change is the Ride Armors. You no longer need to get the Chimera Armor in Blast Hornet’s stage to access the other Armors. Collecting an armor piece will give you immediate access to it, whether or not you already collected the Chimera Armor.

All of these changes make the experience much more manageable and gave me an appreciation of X3 that I never knew I could show.
