There is the .MOD files :
  English mod file :

 And my .MOD files "converted" (I believe...)

 If anybody can look at them, and maybe find what I did wrong... 
 Thanks!
 Hi, I looked at a dialog file from 301NAR.MOD in your K2-fr.zip file and saw it still retained English substrings. I used K-GFF to determine this. 
 Try going through these steps to perform your conversion. 
 1. Download ERFEdit and K-GFF.
 2. Create a folder called "MOD" and use ERFEdit to extract the entire contents of an English MOD file into the "MOD" folder.
 3. Create a folder called TempMOD. Put DLGCONV.exe into this folder.
 4. Open a command prompt and change directories to TempMOD.
 6. Type the command: dlgconv.exe -i ..\MOD\*.* -o . -t 3. 
 This will create French versions of the .uti, .utc, and .dlg files in the TempMOD folder. the "-o ." portion of the command is the only output option that doesn't cause dlgconv.exe to bug out. I see I need to fix that. :o
 6b. Test one of the .dlg files by opening it with K-GFF. Press F9 to do a Search by StringRef and search for -1. Look at the substrings under the entry that is found, they should show Male French and Female French.

 7. Move the files back over to the MOD folder, overwriting the English versions.
 8. Use ERFEdit to create a new .mod file and add all the files from the MOD folder.
 9. Repeat for each .mod file. 
 Here's one I did for 301NAR. (link) (

 Edit: Tell you what... since this utility needs fixing anyway, I'll see what I can do about integrating a .mod conversion function. I'm sure you're not the only one who's faced this frustration. :)
