nope. It works as it is. If i recall correctly you need to have lnkdatas.bin in the same directory and unite every dataXXX.bin in one file.
The tool should do that for you but if it doesn't work, use this command:
copy /b data000.bin + data001.bin + data002.bin + data003.bin + data004.bin + data005.bin + data006.bin + data007.bin + data008.bin + data009.bin + data010.bin + data011.bin data.bin
Thanks for both the tool and this description that made the tool work right. I've started to excavate and play with visualizing the item data in ways I missed while playing the game at the most and probably would have lost interest before coming to the fun part of doing stuff with the data, had I had to do crack open the binary formats from scratch.
