Shin Sekaiju no Meikyuu: Millennium no Shoujo [Decrypted] 3DS (JPN) ROM interface on Windows

Shin Sekaiju no Meikyuu: Millennium no Shoujo is a dungeon-crawling RPG developed by Atlus and published by Nintendo, released in Japan on June 27, 2013, for the Nintendo 3DS. This decrypted ROM lets you play the game on Windows using the Citra 3DS emulator. You'll explore intricate labyrinthine dungeons, build a party of customizable characters, and uncover a story that spans a thousand years. The game is entirely in Japanese, so a basic understanding of the language or a translation guide is helpful.

If you're a fan of first-person dungeon crawlers like the Etrian Odyssey series (which this game is a spin-off of), you'll find familiar mechanics here: mapping your progress, managing resources, and engaging in turn-based combat. The "Millennium no Shoujo" subtitle refers to a girl who has lived for a millennium, tying into the game's mysterious narrative.

This page provides the decrypted ROM file (415MB) that you can run on Citra. The download is free, and no password is required to extract the archive. Below you'll find the download button, technical details, and guidance on getting the game running.

    • Engaging dungeon-crawling gameplay with a strong sense of exploration.
    • Deep character customization and party-building options.
    • Decrypted format simplifies emulator setup.
    • Compelling story that ties into the Etrian Odyssey universe.

Gameplay Overview

Shin Sekaiju no Meikyuu: Millennium no Shoujo is a role-playing game that puts you in control of a guild of adventurers exploring the Yggdrasil Labyrinth and other mysterious dungeons. The game is played from a first-person perspective, and you move in grid-based steps. As you explore, you'll need to map out each floor, noting shortcuts, resource points, and dangerous areas. Combat is turn-based, with your party facing off against monsters and bosses. You'll manage HP, TP (skill points), and items to survive.

The game features multiple character classes, each with its own skill tree. You can create custom characters, choose their class, and develop their abilities as they level up. The story revolves around a girl named ... (the Millennium no Shoujo), who has a connection to the labyrinth. As you progress, you'll uncover her past and the truth behind the dungeon.

For those familiar with Etrian Odyssey, the core loop will feel familiar: explore, map, fight, and return to town to restock and heal. The game adds its own twists with the story and character interactions.

Installation and Setup

To play this ROM on Windows, you'll need the Citra 3DS emulator. Citra is a popular emulator that can run decrypted 3DS games. Here's a general outline of the process:

  1. Download the ROM from the link on this page.
  2. Extract the downloaded archive using a tool like WinRAR or 7-Zip. The file is in .3ds format.
  3. Download and install Citra from its official website (we link to a guide below).
  4. Open Citra, click "File" > "Load File", and select the .3ds ROM file.
  5. The game should start. If Citra asks for shared fonts or shows errors, you may need to obtain the shared fonts (see the note below).

Note: The ROM is decrypted, so you don't need to perform any decryption steps. However, Citra may require shared font files to display text correctly. You can find the shared fonts from the Citra setup guide on our site: Citra 3DS Emulator.

For extracting RAR files, use WinRAR or 7-Zip. There is no password on any game files we upload, so you can extract without a password.
