🔴 Advanced Setup (Need Installation)

Server Setup (Only do once for each OCR method):
- Click the SetupOCR button to start setting up the server based on the OCR method you selected in settings (If you selected Windows OCR, you can skip this step)
- Setup can take 5-15 minutes, depending on your internet speed and computer power
- Wait until the server setup is complete, you will see a message "... environment setup completed"

- Click the StartOCR button and wait until you see the message "Successfully connected to .... server" (If you selected Windows OCR, you can skip this step)
- Select translate region (ALT+Q or Click SelectArea button)
- Click Start button (ALT+G) to begin translation

LLM Setup:
- Go to settings and add your Gemini API key. There are instructions on how to get the API key there.
- You can enter multiple API keys, press Enter after entering each API key.
- Check the other settings; the default values should be fine. Note that there is a place to enter the name of the game, which is important! The LLM knowing this will help it fix errors and create better dialogue.

Note: The first time you use EasyOCR or PaddleOCR with a new language, it has to download first! So it might seem like it's not working, just wait a minute or two and start/stop the application's translation, it will work.

❓ Frequently Asked Questions (FAQ)

What languages can RSTGameTranslation translate?

The software can translate most languages, but it's primarily tested with Japanese to English and English to Vietnamese translations.

I don't have an NVIDIA GPU, can I still use it?

Yes, but performance will be much lower as it will use CPU (30-50% capacity). You can try using Windows OCR for lighter performance.

Can I use RSTGameTranslation without an internet connection?

Yes, you can use Ollama or LM Studio to run 100% offline. You'll need to download the LLM models to your machine first.

How do I get a Gemini API key?

You can sign up for a free Gemini API key at Google AI Studio. After logging in, you can create an API key in the settings section.
