mark of the ninja tools

[Amin Mohebbi]

Hello,

I’m working on adding Persian (Farsi) language support to Mark of the Ninja Remastered. The game uses a custom engine with fonts stored as .fnt (bitmap font descriptor) and .tex (texture atlas).

I’ve already tried extracting and editing the files, but I ran into these problems:

1. The engine doesn’t support RTL (right-to-left) text or Arabic script shaping.

2. I couldn’t find a proper tool to generate .fnt + .tex fonts that are 100% compatible with this engine.

3. Even when I managed to replace some characters, the game only shows them left-to-right and disconnected.

What I need is a tool or workflow that lets me:

Create or edit bitmap fonts for the game (.fnt + .tex).

Replace existing font textures with a new one containing Persian characters.

Ensure the files are repackaged correctly so the engine can load them.

If anyone has experience with Klei Tools or other converters for .tex/.fnt files, I would really appreciate detailed guidance. My goal is simply to add a working Persian font, even if RTL shaping is limited.

Thank you in advance for any help or advice!
