🎮 What is GameStringer?

GameStringer is a desktop application (Windows & Linux) that lets you translate video games that don't have your language.

Most games store their text in files — JSON, XML, CSV, .locres, .rpy, BSA/BA2, CPK, Unity Localization StringTables, and many other formats. GameStringer scans your game folder, finds those files, sends the text through an AI translation provider of your choice (OpenAI, Claude, Gemini, DeepSeek, Ollama, 20+ more), and patches the translated text back into the game. One click, no technical knowledge needed.

For Unity games that lock text inside compiled assets, GameStringer automatically installs BepInEx + XUnity.AutoTranslator — no manual setup. For Bethesda games (Skyrim, Fallout, Starfield) it parses BSA/BA2/ESP natively. For CRI Middleware games (Persona, Yakuza) it handles CPK/CRILAYLA/MSG/BMD. For Unreal Engine it edits .locres directly.

It's not a machine translation website. It's a full pipeline: analyze with P.T. → detect engine → extract text → translate with AI → quality check → patch back → play.

🚀 How it works

1. Install GameStringer and launch it
2. Your game library loads automatically — Steam, Epic, GOG, Origin, Ubisoft, Amazon, itch.io (800+ games detected in seconds)
3. Pick a game → optionally run P.T. (Prediction Tool) to see difficulty, estimated time, best LLM chain
4. Click "String it!" — GameStringer scans, extracts, translates, and patches automatically
5. Play in your language — backups are always created before patching

That's it. No command line, no manual file editing, no modding experience needed.

🧠 The Prediction Tool (P.T.)

The most powerful feature in GameStringer. Don't start a translation blind — analyze first.

P.T. is a deep analysis engine that runs before any translation. It scans your game folder, detects the engine, estimates the volume of translatable text, and tells you:

• Difficulty Score 0–100 — combined weight of string volume, engine complexity, DRM, encoding, linguistic challenges
• Estimated time across 18 LLM models — Ollama (Gemma 4, Qwen 3, Llama), OpenAI GPT-4/4o, Claude 3.5, Gemini, DeepL, DeepSeek, Groq
• 5 recommended LLM chains: Local (privacy), Cloud (quality), Hybrid (balanced), Budget, Premium — each with cost and quality score
• DRM detection: Denuvo, VMProtect, Steam DRM, EAC, BattlEye — warns before you try
• Encoding analysis: Shift-JIS, UTF-8, UTF-16, Big5, EUC-KR detected per-file
• Translation complexity: honorifics, gender agreement, RTL, ruby/furigana, CJK-specific handling
• Confidence score and workflow plan — the exact steps that will run when you click "String it!"
• Export report (JSON + Markdown) for sharing or archiving

P.T.Rank — Quick Ranking

After running P.T. on multiple games, open P.T.Rank to see all analyzed titles sorted by difficulty. Perfect for planning your translation queue: start from the easy wins, save the 800k-string RPGs for last.

Dry Run Scanner

Don't want to analyze one game at a time? Run Dry Run from the Library page to scan your entire Steam library (800+ games) in batch, with zero file modification. You get a JSON report categorizing every game as Ready (engine supported + strings extractable), Errors (manifest issues / DRM blocker), or Unsupported (unknown engine / no text). Progress is real-time, and no backup is needed because nothing gets touched.

String it! Smart Gate

The "String it!" button on the game detail page is smart: if the game has already been analyzed by P.T. within the last 24h, it launches the translation wizard directly. Otherwise it suggests running P.T. first (with a one-click "Run P.T. first" / "String it! anyway" choice). No more wasted runs on games that turn out to be DRM-locked or 5-minute affairs.

Unity games get special treatment: if no translatable files are found, GameStringer detects it's a Unity game and offers to automatically install BepInEx + XUnity.AutoTranslator with one click. Just launch the game once after install, then re-scan — all text becomes translatable.

⚠️ Anti-Cheat Warning: BepInEx (DLL injection) can trigger anti-cheat systems (EAC, BattlEye, Vanguard). GameStringer includes anti-cheat detection and will warn you. Only use on single-player / offline games. P.T. detects DRM before any modification.
