It containts 68 DLC packs for the European version of Tales of Xillia, translated from Japanese to all languages the European version supports. Keep in mind that the translation can be quite different from the official EU DLCs as (almost) no text from them has been used. If you wish to use the official DLCs, just installing them over this pack should work.
The pack is labeled 0.9 because it's missing 2 DLCs:
- 300,000 Gald (3)
- Growth Promotants! Red Herb Set
Those 2 DLCs aren't included in any of the "complete" packs around and any effort (well, not really that much effort) trying to forge them so far has been in vain so this is most likely the final version.
