I tried this and it worked but with some problems... When I tried to open a skit (The legend of peachtaro) the game crash and says the installed data is corrupted or something like that. Maybe there are more skits like this but I didn't try much.
I have the undubbed root but without fixing the skits.
First, thank you very much Mamu for your tremendous work on this undub. I'm really grateful!
Now I f I may ask, can anyone tell me how much is translated and what is still not. I tried running througout the whole 60 pages but what I got is at first the Skits and menus couldn't be remplaced by the US files so they needed some manipulation and a new translation. Now I've read that the menu and Skits got fixed. So what is still missing?
Only for the curious ones: Here is some tools to extract dialog and other files for Tales of Xillia TLFILE.TLDAT, that might also work for other files. It use the same way as Tales of Graces F. That could give some interest to those who want to make a translation or try to undub it once the localized version comes out.
