I downloaded a translation pack and copied it over to the game folder. The pack includes
swkotor2.ini
dialog.tlk
3dm32.dll
binkw32.dll
and a 3DMGAME folder containing 3DM.tff, 3dm.dds, 3dmloc.ini.

After overwriting the files, some parts of the game did change to my language, but the text boxes started showing missing text issues. Since this translation is very niche and I can't contact the original creator, I'm wondering if anyone can help me with this problem?
