Hey. With the english release of Dynasty Warriors 8 game I've played a bit of Jin Dynasty segment and have provided a save for whomever decides to do the trainer.
Here's a link:
It contains two files, since I wasn't sure which you can work with.
File of size 708 KB is extracted directly from the save on USB.
DAT File of size 651 KB was extracted from the contents of the save, after I doubleclicked on the save, so that the little window with Rehash and other options appears.
