If you are determined to run this specific, obscure build (official or creepypasta mod), here is the general methodology. Always scan downloaded .exe or .jar files with antivirus software, as these legacy files often exist in grey-area digital archives.

A "Portable" build is modified or wrapped (often via a custom batch loader or modified launcher directory configuration) to keep the data, runtime assets, and world saves in the exact same folder as the execution file. This allows retro gamers to run the entire historical environment natively from a USB flash drive or isolated desktop folder without altering their modern, official launcher settings.
