I have done some work on the multi-language side of Gnucleus, and have started using RC-WinTrans 5.5 Lite for distributing files for translation and building multiple .rc files.
So far I have introduced German and Japanese Languages. I already had a German one, but in the process I lost it all (oh darn, right?).
Please download the language of interest or if it's not there, download one and change everything to your language:
The files are in .CSV format so you can open them up in your favorite spreadsheet and edit them with ease. Please e-mail them back to me when finished. at nathanbrown@dittosrush.com or post them into the patch manager on our page in sourceforge.
