Dual JP-EN Text for VO mod

Octopath Traveler 0 – Dual JP-EN Text for VO mod

Adds Japanese above the existing English subtitles only for voiced (VO) TalkText lines, and updates the UI font so the Japanese characters render correctly. Pick ONE of the three included .pak variants depending on whether you want romaji and/or furigana.

Requirements

•    Set the game’s Text Language: English

•    Set Voice Language: Japanese

•    This mod only affects lines that have VO. Everything else in the game remains all English.

•    The random things that characters say in battle (which have no subtitles to begin with, e.g., “Sateto” (さてと)) are not subtitled, for obvious reasons.

Included Versions (one 7z, pick ONE pak)

•    DualLanguage_P — Full version: Japanese with furigana + romaji + original English (3-line stack)

•    DualLanguage_NoRomaji_P — Furigana version: Japanese with furigana + original English (2-line stack; no romaji)

•    DualLanguage_Basic_P — Basic version: Original Japanese + original English (2-line stack; no furigana, no romaji)

Files Edited

This mod edits these assets (and will conflict with any other mod that edits the same files):

•    ./Octopath_Traveler0/Content/Local/DataBase/GameText/Localize/EN-US/TalkText/GameTextEvent.uasset

•    ./Octopath_Traveler0/Content/Local/DataBase/GameText/Localize/EN-US/TalkText/GameTextEvent.uexp

•    ./Octopath_Traveler0/Content/UI/Font/9PCS_Rocio_Default.ufont

What You’ll See In-Game

For affected VO subtitle lines, the display becomes:

DualLanguage_P (3-line stack)

1.    Japanese line with furigana in Aozora-lite format: 漢字《かな》

2.    Romaji line (italicized) for the same Japanese text

3.    The original English subtitle line

DualLanguage_NoRomaji_P (2-line stack)

1.    Japanese line with furigana in Aozora-lite format: 漢字《かな》

2.    The original English subtitle line

DualLanguage_Basic_P (2-line stack)

1.    Original Japanese line (unchanged)

2.    Original English subtitle line (unchanged)

•    DualLanguage_Basic_P does not rewrite or reflow either language at all—just JP + newline + EN.

•    The furigana/romaji builds may occasionally drop existing English line breaks where needed for layout; English wording itself is not rewritten.

Font Changes (Why 9PCS_Rocio_Default.ufont Is Modified)

The default UI font does not include full Japanese glyph coverage. This mod updates:

•    9PCS_Rocio_Default.ufont

Japanese glyphs were carried over from:

•    9PCS_Now_Std_GB.ufont

So the Japanese overlay renders correctly instead of showing nothing.

Installation

Drop ONE of the included .pak files into the ~mods folder for your store version:

Microsoft Store / Xbox app

•    XboxGames\OCTOPATH TRAVELER 0\Content\Octopath_Traveler0\Content\Paks\~mods

•    SteamLibrary\steamapps\common\Octopath_Traveler0\Octopath_Traveler0\Content\Paks\~mods

If ~mods doesn’t exist, create it.

Compatibility

•    Incompatible with any mod that edits GameTextEvent.uasset/.uexp (EN-US TalkText) or 9PCS_Rocio_Default.ufont

•    Generally compatible with mods that don’t touch those files

•    Some unvoiced lines may accidentally receive dual language bubbles.
