Wow! Thanks for your effort, you've really done quite a bit of work already, and it is impressive.
Decompilation is the best way to do this right now, but it is still far from ideal. I think Steam Workshop might be the place to upload it after I get that set up (soon!). However, it will need to be recompiled each time the game receives an update, which is why I think you may want to wait for me to figure out a better system for localization.
I want to make this easier for translators like yourself, by implementing a "language pack" system, where all of the text in the game will be stored in a simple text file for each new language. My plan is to host it on Github so that anyone can help work on it.
Currently the text data is scattered all over the place and that's something I need to fix. Honestly, I'm kind of afraid to start, since it will be a big job that touches code all over the game and can introduce bugs. However, seeing the effort you've put in and the enthusiasm of other translators, I feel that I should hurry up with it! I will try to do so within the next few months. If you'd like, send an email to Fishlicka@gmail.com so that I have your contact info, and I will email you when it is ready.
Out of curiosity, what language are you working on? ^^
