Yes, it is working now. Thank you a lot. But your guide isn't perfect, i wasted more than 1 hour to force it to work, so, i can give some advices (maybe, they are actual only for me, i don't really know).
So, you should start the game on your ios device at least once before replacing files, otherwise it will not work. After creating a backup replace the files in container/documents
Also, you should enable the internet connection on your ios device before starting the game, and click on the button "use the files and load the game" or something like that.
Thank you for this work, it is a really cool thing.
