The record

Purpose: LCE2JE converts Minecraft Legacy Console Edition Windows64 .ms world saves to standard Minecraft Java Edition 1.6.4 saves.
Target build: The converter is specifically designed for the leaked Windows64 build of Legacy Console Edition.
User interface: It provides an interactive, cross-platform graphical user interface for the conversion process.
Windows download: Windows users can download a standalone portable lce2je.exe executable.
Linux download: Linux users can download a standalone lce2je.AppImage executable.
Dependencies: The precompiled Windows and Linux binaries do not require Python or other dependencies to be installed.
Player mapping: The converter scans player profiles and lets the user choose which profile becomes the Java Edition host.
Conversion pipeline: It extracts the proprietary .ms archive, converts binary chunk formats, translates NBT structures, and reconstructs a Java Edition 1.6.4 world folder.
Output handling: After conversion, the output folder opens automatically and can be copied into .minecraft/saves.
Reverse conversion: The repository also includes command-line scripts to convert Java Edition 1.6.4 worlds back into LCE format.
Modern-version compatibility: The pipeline sanitizes proprietary LCE string UUIDs and rebuilds standard Java Edition UUID integers to help prevent crashes when upgrading converted worlds.
File safety: Converted chunks and metadata are written through temporary .tmp files so interruptions do not leave partially written files.
License: The software is licensed under the GNU General Public License version 3.0.
Windows warning: The standalone Windows executable is unsigned by default and may trigger Windows SmartScreen or antivirus warnings.
