Hi everyone — let's celebrate!

RPG Maker MV turned 10 years old — a decade of creativity, unforgettable projects, and a thriving community. To honor that milestone, I'm excited to introduce rpg_locale is a lightweight, developer-friendly i18n system built specifically for RPG Maker MV.

It gives you fast, flexible multi-language support, tools to extract and edit text, and an offline automatic translation option so you can localize quickly and privately — no internet required.

Why you need it?​

Localization shouldn't slow you down. Whether you're building an indie RPG or updating an older project, rpg_locale helps you:

• Reach more players with multi-language support.
• Speed up translation workflows with smart extraction tools.
• Translate securely and quickly without depending on online services.

Core features​

• Translation Helper — automatically extract text from your JSON files so you can send clean, organized payloads to translators or translation tools.
• Editable Translation UI — review and edit every string inside an editor-friendly interface, perfect for manual refining and context-aware corrections.
• Local Automatic Translator — a built-in offline translator that supports many languages without internet access; ideal for rapid prototyping and private, local builds.
• rpg_locale.js plugin — ready to install via the RPG Maker MV Plugin Manager for instant multi-language support; includes automatic word-wrap support that inserts line breaks where appropriate to preserve layout and readability.

Designed for creators​

RPG Locale is built with RPG Maker MV conventions in mind:

• Easy integration: drop the plugin into your project and it detects standard JSON structures used by MV.
• Non-destructive workflow: extracted strings are tracked separately so your original files remain intact until you apply changes.
• Extensible: add custom translation backends or export formats to fit your pipeline.

How to get started​

1. Install the plugin in your project's js/plugins folder.
2. Run the Translation Helper to extract strings from your JSON assets.
3. Edit translations using the built-in editor, or export the bundle for external translators.
4. Use the local automatic translator for quick bulk translations, then refine manually for best results.

Use cases​

• Rapid multi-language playtests during development.
• Community-driven localization with clear extraction and import tools.
• Private, offline translation workflows for studios that need local-only processing.

Part of RPG Maker MV Ace​

rpg_locale.js is part of the RPG Maker MV Ace project — an effort to modernize the MV engine with current web technologies and meaningful quality-of-life improvements for game developers.

Notes​

This GUI for creating user interface is designed with WxFromBuilder using internal script to convert the result into generated html code followed by manual adjustment. A critical part of this plugin requires patching the core RPG Maker MV scripts (like command 101, command 102, command 105, etc.) to intercept text rendering and load strings from generated *_i18n.json file instead. AI was used as an advanced analysis tool to deconstruct and understand the text-rendering pipeline within the RPG Maker MV codebase. This AI-assisted analysis was essential for me to gain the necessary insights to author the precise, clean, and efficient patches required to hook the localization system into the engine.
