I've collected most languages files for the game, and made them available for downloading in the old spud forums[web.archive.org]. Since these are closed now, I decided to make a new guide here.

To change the language of the game, 2 files are needed for conversion between Western European languages[EN-FR-GE-IT-SP] and a 3rd one if you convert to or from Polish or Russian;

the two files always used are:
- MP2_(language).ras
- Movies/Previously.bik

The third file is only needed for conversion of CD install from Polish or Russian to Western European is (it contains the proper character set for these languages):
- MP2_Data.ras

- Install the game, from cd or from steam.
- Rename your current MP2_(language).ras file to MP2_(language) without extension.
- Place the new language file in the main game directory.
- Rename Movies/Previously.bik to Movies/Previously without extension.
- Place the new movie file in the movies directory.
- Do the same for the MP2_Data.ras file if needed.
- Done

- Remove all files you installed and rename the originals back, with the proper extension.
- Done

- saves will still work after changing language

I don't suppose anyone needs these because I included them in the Russian and Polish downloads, but just in case; here are the respective datafiles for converting Western_European to Russian or Polish.
- Russian data file, needed to convert English to Russian, cyrillic character set: MP2_Data[RU].rar (130,9 MB)[drive.google.com]
and Polish data file: MP2_Data[PO].rar (130,9 MB)[drive.google.com]

- I think at least German and French where created by fans, and not the original publisher.
