Ok so this is pretty easy. I have discussed it with Tekken and it may be added as a feature in a future update to XPacker but until then here is how you do it manually.
1. You will need a bik file that is 320x320 (the bottom 100x320 should be blank because it wont show on the titantron)
2. Choose an empty titantron slot (I have been using 823-949) and name the file with that number and make it bik2 eg. 823.bik2
3. Copy your SaveData.dat from your xbox and extract it to your deskt
