"Super Save File!" Made by playing with the excellent Mega Man X5 Improvement Project Addendum patch (v1.5) found here. Still compatible with the original US version though! Data files 1 through 6 are in use and feature: All eight Mavericks defeated. All Life Up and Energy Up upgrades obtained (applied to both X and Zero!). All parts obtained. All armors available for use (including X's Ultimate Armor and Black Zero) and Zero's Buster is still functional.
