I have never done font editing before. Today I tried it on this game, but the letters I changed appear in their original form in the game, as if no changes were made. I edited it using the Photoshop DDS plugin. I modified these characters: "î", "ý", "ō". I’m attaching both the original and the edited files. I don’t know what I did wrong.

Maybe the game didn't load the changed DDS file?

You should leave the edited file (DXT5 compressed) uncompressed as the original is.

(Another (less important?) thing is that the edited dds has 298 unique colors while the original has 255 only.)

I noticed that. However, even after deleting all saved game data, the problem persisted.

I didn't know the settings. I saved the file with Photoshop standard (DXT5) settings.  

Is it supposed to be like this:

Which are the other format options?

Your edited file is compressed (one 4th of the original size) so you should save uncompressed, like the options show.

I saved the settings I just sent you and tried again. But it's still the same, nothing changes.

These are all the settings:

There is also a setting called alpha channels that is not visible in the image. It is selected.

When you choose "uncompressed" the file size should be bigger than for a DXT5 file.

I'd try some other tool, maybe Gimp, for testing.

It's exactly the same size as the original file. However, as I said, the problem persists.

Then a byte-to-byte comparison could shed a light on this.

But you'd need to asure that the game loads the file.

edit: it's PS3 (A tool like "Process Monitor" would help.)

edit: see link in my next post

So you could use a hex editor to change some dozens of FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF blocks in the original DDS into 0A0A0A0A0A0A0A0A0A0A0A0A0A0A0A0A (for example).

If the font isn't affected in game the file isn't loaded.

(Keep backups of original files, btw.)

First of all, I'm sorry for replying a little late. 

To see if the game could read DDS files, I deleted the DDS files from the game folder and then started the game. The game opened normally with the original font:

Now the game is either reading fonts from ".abc" files or cached DDS files. This cache data is not visible on the PS3. However, I can place the DDS files I edited into the pkg file and reinstall the game. This way, if the game reads the font via DDS, it should work. My question is, can the game read fonts from ".abc" files? (These files are in the rar archive in my first message)

I have no idea (don't have a PS3).

Maybe using a PS3 debugger will help.

*.abc is font map. Maybe you can add some characters in it.

Now for the texture. Original is 32 bit rgba, yours is DXT5 which is not exact as org. Also i noticed you didn't change alpha channel of the char which is crucial for correct display.

This is the font game uses.
