Metal Max 4: Gekkou no Diva Update 1.1 & DLC [Decrypted] 3DS (JPN) ROM brings the post-apocalyptic tank-battling RPG to your PC through the Citra 3DS emulator. Released in Japan on November 7, 2013, this entry in the long-running Metal Max series was developed by Cattle Call and published by Kadokawa. The package you see here includes the base decrypted ROM, the 1.1 update, and the DLC content, all prepared for use with Citra. If you enjoy monster-hunting RPGs with a vehicular twist, this is a rare import worth exploring. The game is entirely in Japanese, so a basic comfort with the language or a translation guide will help you get the most from the story and menus.

This update article covers what the 1.1 patch and DLC add, how the decrypted files fit into the Citra workflow, and what to expect from the game's systems. You'll find the technical specifications, a download button, feature highlights, and practical notes on getting everything running. The files are small—the update is around 2MB and the DLC around 25MB—so they won't strain your storage. The base ROM is a separate download linked below.

Technical Specifications

What Metal Max 4: Gekkou no Diva Offers

Metal Max 4: Gekkou no Diva continues the series' signature blend of open-world exploration, turn-based combat, and heavy customization. You play as a hunter in a ruined world where humans scrape by and machines rule the wasteland. Instead of traditional fantasy classes, your progression revolves around tanks—called "vehicles"—that you outfit with cannons, machine guns, and special equipment. Combat pits your party and their rides against mutated creatures, rogue robots, and rival hunters. The "Gekkou no Diva" subtitle (Diva of the Moonlight) hints at a story centered on a mysterious singer and the conflicts surrounding her.

The game's structure lets you accept bounty contracts, explore towns, and delve into dungeons. You can recruit party members, each with their own skills, and switch between on-foot combat and vehicle battles. The 1.1 update addresses balance and stability issues from the launch version, while the DLC adds extra content such as new missions or items. Since the files here are decrypted, they are intended for use with Citra and similar emulators rather than original hardware.

Pros & Cons

• Pros:
  • Unique tank-customization RPG mechanics not often seen in the genre.
  • Includes both the 1.1 update and DLC in one package.
  • Small file sizes make downloading and storing easy.
  • Decrypted ROMs work with Citra without extra decryption steps.
• Cons:
  • Japanese language only—no official English localization.
  • Requires a separate base ROM download; this package is update and DLC only.
  • Emulator performance varies by hardware and Citra version.
  • Some menus and story text may need translation tools.

Update 1.1 and DLC Details

The 1.1 update is a small patch (about 2MB) that refines the game's balance and fixes known issues from the initial release. The DLC package (around 25MB) adds extra content that expands the game beyond the base campaign. Both are provided as decrypted CIA files, which you can install in Citra's emulated NAND or load alongside the base ROM depending on your setup. Keep in mind that the base game ROM is not included here—you'll need to download it separately from the link below. The update and DLC are region-specific to Japan (JPN).

Installation and Compatibility Notes

These files are decrypted, meaning they are ready for emulators like Citra without needing a decryption tool. On Windows, you can use Citra's "Install CIA" option to add the update and DLC to your emulated system. If Citra asks for shared fonts or throws archive errors, you'll need to obtain the shared fonts from a reliable source—the original article points to a Citra setup guide. For extracting the RAR archives, use WinRAR or 7-Zip. There is no password on the files. If you encounter CRC errors, re-download the affected part. The game is designed for the Nintendo 3DS, so emulation quality depends on your PC's capabilities and the emulator build you use.

For more RPG and action titles in the download library, you might also enjoy UnMetal Free Download (v1.0.11), a stealth-action parody with a similar retro spirit, or Tears of Metal (v0.13.58591) for another metal-themed experience.

Who This ROM Is For

This package suits players who already have the base Metal Max 4 ROM and want to bring it up to date with the 1.1 patch and DLC. It's also for fans of Japanese RPGs who don't mind navigating menus in Japanese and are comfortable with emulator setup. If you're new to the series, be aware that Metal Max games are known for their nonlinear structure and tough encounters—this isn't a guided, story-heavy RPG. The decrypted format is a plus for Citra users, but you'll still need to manage the base game separately.

Trust and Version Freshness

The update and DLC files here correspond to the Japanese release of Metal Max 4: Gekkou no Diva. The 1.1 update is the official patch from the game's publisher, included as a decrypted CIA. The developer listed for this package is Berry, who prepared the files for distribution. No malware scanning or cleanliness claims are made here; you should always verify files with your own security tools. The download links point to third-party file hosts—1Fichier, OpenLoad, LetsUpload, and ZippyShare—so availability can change. If a link is dead, check the site's reupload request page.
