* Poke Sav is a ROM hacking tool: Its primary function is to modify game data, including text, but it doesn't provide an interface for directly entering Japanese characters.
* Japanese uses a different character set: The Japanese language uses a different character set (hiragana, katakana, kanji) compared to the standard ASCII characters used in Poke Sav's interface.
To use Japanese in your Pokemon ROMs using Poke Sav, you need to:
1. Find pre-made Japanese text files: Search online for Japanese ROMs or fan-made translations for the specific game you are working on. These files will contain the Japanese text already formatted for the game.
2. Import the text files into Poke Sav: Replace the original text files in your ROM with the Japanese ones. You'll need to use a ROM editor like the "Text Editor" function in Poke Sav to find the correct locations to replace the text.
3. Test and adjust: After replacing the files, test your ROM to make sure the Japanese text is displayed correctly. You might need to adjust the font sizes or other settings within the game to ensure readability.
Important: Using pre-made Japanese text files is the easiest and most reliable way to add Japanese to your Pokemon ROM. Creating your own Japanese text for Pokemon games can be very complex and requires advanced knowledge of ROM hacking and Japanese character encoding.
