This V4.0 is a complete and entirely new rewrite of the original Zero Project, thus separating itself from the original version and being more of a 'base' for any other future mods intended. While the general idea of Zero being fully playable is still the same, many other alterations have been added to distinguish itself from the original game and it's previous version.
The new version started back again in late 2017 to fix up many of the original issues and went even further to include many features that were intended from the beginning and then some. A few of the new features included are a new save/load game system, the Frog Armor being properly usable on land, the Black Armor actually doing something for Zero and New Game+!
This project is technically finished, but it may receive more updates or add-ons in the future. For now, with a ton of input from the community, hopefully this 'completes' Mega Man X3 much more than before!RHDN Project PageRelevant Link
