I do not know of a source for $63 xdf. A quick search reveals many people asking for a definition, and although every piece of the puzzle exists to make one, no one seems to have done it. I do see a note on thirdgen that the $0D file may work so if you're feeling brave you might want to load that one up and see what happens.

If you get excited you should note the disassembly I previously linked gives everything needed to correctly view the data and to make a new xdf or to modify an existing xdf.
