Mega Man X3 Zero Project. Play as Zero throughout the entire game plus other enhancements.
Gameplay features:
-Zero is fully playable in stages that he CAN be played in. (IE: Can't switch to him in introduction, but he can be usable anywhere else).
-Zero can use all sub-weapons at the cost of double usage.
-Zero can refill energy tanks and weapons.
-Zero can obtain capsules, heart tanks, energy tanks and ride armor chips, though, Zero may not receive all benefits of the capsules.
-Zero has a 'Black Armor' in the Golden Armor capsule.
-Zero's Z-Sabre animation is much quicker in the air and on the ground.
-Inserted the unused buster frames of Zero for smoother transitions.
-Zero can now charge up all weapons and have his own animations with them.
-Zero CANNOT use the Hyper Chip
-X's buster animations have been hastened in air and ground.
-X's Z-Sabre animation is slightly faster.
-X's vertical dash animation is slightly quicker.
-You can switch characters on the stage select screen WITH an icon change by pressing a button on the 'X' icon.
-X and Zero are swapped in events. Unfortunately, X does not show his armors in them even if he has them. (Hard bug to work around).
-X and Zero each have their own banks of text that allow full customization of dialogue if so desired.
-Frost Shield launches quicker.
-Tornado Drill launches quicker.
-Triad Thunder's charged animation is much, much faster with a new sound to feel more impactful. -Screen shaking doesn't begin UNTIL you punch the ground.
-Energy tanks do NOT drain entirely if you use it to restore a little health. It restores what's needed, that is all.
-Zero can use Ride Armors with his own set of sprites.
-Z-Sabre has been heavily nerfed to compensate for Zero being playable.
-Golden Armor/Black Armor can be saved into the password system now.
-Air Dash/Vertical Dash code has been revised heavily. No longer does it check specific animation sequences, rather, it uses a 'fixed' number to set the amount of jumps you can do.
-Capsules no longer show armor pieces being placed onto the character. This caused SEVERE bugs throughout the game.
-Capsules now repeat their lightning wrap around animation three times to compensate for the flash feature being removed.
-X and Zero have their own section now for animation data, VRAM data and sprite assembly relating to them which allows full customization and plenty of spare room for new animations and sprites.
-You can Buster and Z-Sabre combo instantly with Zero only.
-You can chain charged buster shots on bosses instead of having to wait for the flash to go away to perform another attack. Ride Armor bosses are an exception.
-If you're already in the air with Zero, pressing jump again will allow you to double jump if you have the corresponding upgrade.
Now with MSU-1 compatibility. Here's the MSU-1 soundtrack:
For the SD2SNES or if you want to play it on an emulator. Google "epforums mega man x3 zero project msu-1" to find the MSU-1 version for use on the SD2SNES. MSU-1 version only works on bsnes or higan emulators.
Anybody have a SD2SNES? This is one of my favorite things to play on it.
