If anyone is interested, I've mapped out every data piece in the Journal Data. Amazingly, the only difference between the Xbox and PC version is that the numbers ID'ing the section as a Journal and giving the index numbers are shorts (2 bytes) instead of longs (4 bytes) on the PC.
So the number ID'ing the data as a Journal instead of a Dialogue option loads in the editor, but the index is in the wrong place, so it always fails to load right.
I uploading the documents to here
Anyone who has programmed an alternate dialogue and journal editor or who know's one of the people who has, please send me a PM. These documents can allow for modification of the editor for Xbox Journals and soon, perfect Xbox dialogue.
