How to change Font 9-nine

[sainaka]

I’d like to ask about a game using the Kirikiri engine (9-nine). I’ve been working on this issue for over a week, and I feel like I’m at a dead end. I extracted the data.xp3 file to edit the scripts (.scn) and put it back into the game, but the game cannot display my language (thai). I tried editing the config, but it didn’t work. Is there any way to make the game display my language?
