The Ultimate Guide to Shin Megami Tensei IV Apocalypse: Undub, 3DS, and the Patched Experience

The Definitive Guide to Shin Megami Tensei IV: Apocalypse – Undub Patched 3DS Version

What is Undub?

"Undub" refers to a patch released by Atlus to fix various issues present in the original North American and European releases of the game. The undub patch aimed to correct translation errors, tweak gameplay balance, and ensure a more authentic and enjoyable experience for players outside of Japan.

Step 5: Rebuild & Install

  1. Rebuild the CIA file using HackingToolkit3DS (Repack -> new CIA).
  2. Copy the new, patched CIA to your 3DS SD card.
  3. Use FBI (a homebrew installer) on your 3DS to install the patched CIA.
  4. Launch the game from your home screen.

Step-by-Step (Abridged):

  1. Install CFW on your 3DS (follow 3ds.hacks.guide – do not use video tutorials).
  2. Dump your game using GodMode9 to get a .trim.3ds or .cia file on your SD card.
  3. Obtain the Undub files – Typically, you download a folder called romfs or specific .bcstm and .bcsar audio files.
  4. Replace audio files – Using GodMode9’s file explorer or a PC tool like HackingToolkit3DS, inject the Japanese audio into the game’s romfs.
  5. Rebuild the CIA (if necessary) or use LayeredFS (simpler): Place the modified files in /luma/titles/<TitleID>/romfs/ on your SD card.
  6. Enable game patching in Luma3DS’s configuration menu (hold Select on boot).
  7. Launch the game – You should now hear Japanese voices.

Missed English-Only Elements

The Undub does remove one thing: the English battle announcer’s “Mighty hit!” / “It’s super effective!” style lines. Some miss this campiness; others celebrate its removal. Rebuild the CIA file using HackingToolkit3DS (Repack -&gt;

What it does:

A small tool (PC or homebrew-based) that scans your patched .3ds or .cia file (or installed title) and checks:

  1. Audio integrity – Confirms all Japanese voice files are correctly mapped and no missing or mismatched files remain from the original dub.
  2. Text/UI consistency – Flags any leftover English voice references or mismatched subtitle timings.
  3. Save compatibility – Verifies if existing save files (from the original USA/EUR version) can be safely used with the undub patch, and optionally converts them to prevent crashes or missing audio triggers.
  4. DLC compatibility – Checks whether installed DLC (e.g., Fiend, Covenant, Mitama packs) uses undub-friendly assets and warns if any DLC voices will revert to English or cause crashes.
