I use UltraIso, it will let you extract the navboot file from the v29.mds file and save back (the new image) to a v29.iso file (ready for cd burning)

Install UltraIso,
Then run UtraIso
File, Open "v29.mds"
Navigate to "V-2/RR/0101/BMWC01S/app_sw" in the now open image.
Drag and drop the navboot out of the image onto desktop (or sub-dir)
Open navtweak
File, Open "navboot"
Select the 2nd tab (images)

For sky select romicons #8 and right click replace, (with your chioce)
For splash seletct rombitmaps #14 and right click replace, (with your chioce)
For 3d icons rombitmaps select rombitmaps (you get the idea)

Then save the navboot (keep a copy of the original safe).

Then drag and drop into the open UltraIso session (back where you found it, "V-2/RR/0101/BMWC01S/app_sw").

Save the UltraIso image as v29.iso, then burn a cd ad 1x speed.

Thats it.

Hope this helps
