I was trying to search for an answer how to enable using the translation of the game. Is there somewhere the instructions what else has to be done than to get the translated .po file to data/po folder? It would be easier to check if I've understood some of the contexts right if I could actually play the game with that translation.
Both, translating and playing the game with another language I've already uploaded the translation to Transifex. But to make sure that I've understood all of the contexts right I'd like to play the game with the translation.
All you need to do is to copy your translation to <supertuxkart>/data/po/<iso>.po
If your languages hasn't been added to the selection in the user interface yet, you can replace the po file for a language that you don't speak and select that language from the menu.
Thanks for the answer. It's good to know I can test the translation though the language isn't in the language list yet. Is there some way to add it there by myself or does it need a lot of editing the code?
