I have completed bit-perfect digital audio rips of both the US LBX edition LD and the Japanese FS LD with digital sound. I can confirm that the Japanese disc has the original staff-drop sound effect found on the dvd and bd. Both have been synced to the Blu Ray and are ready to go.
Let me know if these are still needed, and I can post them to myspleen, along with Temple of Doom and Last Crusade.
