It is easy to add any other language to the app, with simple steps:
1- Translate the texts file.
2- name your txt file as the one to be replaced, ie, portuguese is 01.txt...
3- from the flags image (I only have the european flags there, sorry) cut your country flag, to the same size as the others, and name it the same as the text file except extension, ie. portuguese flag is 01.jpg.
4-Edit the IN4P.ini file and replace the discarded language name with the new one, ie. language1=Português change to language1=Español
And thats it, you now have your own language set working in my app..
