I still have my complete 1.3.1 directory.. yeah I hoard digital information.
Assuming you wanted the font.ini file in 1.5 format, I edited the 1.5 font.ini file accordingly, and added the 2 fonts used (and you should have them already).
Just extract the files into soldat's directory and all should be fine. Back up your font.ini file first just in case you have edited font size values you'd like to maintain (located in the Txt folder).
