Translating to different languages?

If you want to translate strings you may need to mark them sometime as translatable.
This mean that every in-line string (ie one between " I source code) need to be wrapped with _(...) macro.
For instance " draw count %d" in source code need to be transformed into _("draw count %d&quot
It's already done in some place but some strings in gui weren't properly marked last time I looked. And I think no error message are marked.

Then you need to run some gnu tool that will generate translation file that you can fill to get translated strings. You can open a project on Rosetta too if you want to make collaborative translation.

Well, one problem is - it's only applicable for GUI. Since the rest of rpcs3 is tried to keep as much separated from wx/other frameworks as possible.
