TTDPatch supports a variety of languages. Currently these languages are available: Czech, Danish, Dutch, English, Finnish, French, German, Hungarian, Italian, Norwegian, Polish, Russian and Spanish.
TTDPatch will first try to automatically determine your language by asking the operating system. If you find that this doesn't work as intended, there is another way, for example if you want a different language than your operating system reports.
Set either of the environment variables LANG or LANGUAGE to the language you want. If you select a language that TTDPatch doesn't support it will complain, but also tell you the list of languages it knows.For example, you can put the following line in the batch file which runs TTD, or even in C:\autoexec.bat if you like:
This would select the Dutch language for the output of TTDPatch.
