Supported engine · RPG Developer Bakin
RPG Developer Bakin (SmileBoom, the successor to SMILE GAME BUILDER) powers a growing wave of Japanese indie and doujin RPGs. RuneTranslate translates the text those games carry in their data.rbpack: the whole database (item, skill, character, class, condition, and status names + descriptions) and event / scenario command text. A bundled sidecar drives the game's own engine to read and write the data accurately, then applies your translation through Bakin's built-in localization, set as the game's default language — so the exported build boots straight into your translation, with no in-game language menu to switch. (On newer engine builds without that localization API, RuneTranslate writes the translated text directly, with the same result.) 3D models, textures, and audio are untouched; text compiled into a game's C# battle/menu scripts is out of scope. Verify on a real game before you rely on it.
Bakin databases reuse the same character, item, skill, and place names across hundreds of database entries and event lines, and providers will rephrase them inconsistently from batch to batch. Glossary the protagonist and party, recurring NPCs, key locations, and any signature skill or status term up front so every database field and event message renders them identically. Glossary 101 →
Point RuneTranslate at the game directory (the one containing data\data.rbpack and bakinplayer.exe). Engine detection recognises the BKNPAK container automatically; the bundled sidecar handles everything — no separate install.
RuneTranslate reads the game's own data to list every translatable source-language string (Japanese by default; set any supported source language per project) — database names and descriptions plus event / scenario command text — grouped by type (items, skills, characters, events) so it's easy to work through.
DeepL is a strong default for narrative dialogue; OpenAI GPT-4o or Anthropic Claude handle stylized speech and onomatopoeia better. Free Google Translate or a local model (Ollama / LM Studio) covers menu strings and item names. Provider routing can split short strings to a cheap lane.
On export, RuneTranslate copies the game and writes your translation into Bakin's own localization data, set as the game's default language. Run the exported game and it opens already translated — the engine renders your text natively, no language menu needed.
