--- Comment #14 from Nikolay Sivov bunglehead@gmail.com --- Immediate problem with reader in current Wine is broken support of character references in text content, I have a patch for that. With this patch I can see saved game thumbnails, but loading it will crash the game. Next issue seems to be some sort of failure to grow input buffer properly, it crashes on element with text content of around 34000 chars (expanded 7 times because of ೌ format) according to save file markup.
This will have to wait until 2.0 is out.
