Hey everyone, I just ran head-first into the Bunker Delta CD3 corruption bug the other day. After some digging I seem to have found a fix that doesn't involve downloading the files again.
(All this was done using version 1.27, full install)
I'll try and explain what to do.
1. Go and download CDmage --
http://cdmage.orcon.net.nz/frames.html
2. Rip CD3 to an iso image. CDmage supports just about any ISO format, but I used CloneCD 4.2.0.2 for the job.
3. Fire up CDmage and open the image file.
4. Run "Scan for corruption" in the Action menu.
Note: my disc had a bunch of errors. Most were in "loc-mis_D.bos" and "loc-mis_E.bos", but I did have one error in "spr-character_E.bos". I believe I had 8 errors total, 1 was a "Low" priority and the others were all "Medium".
5. Run "Repair corrupted sectors" from the Action menu. This should fix the "Low" priority errors.
6. Select the "Medium" errors and then run "Rebuild sector fields" from the Action menu. I just clicked okay to rebuild all the fields.
If that worked then all the errors should have a green X or checkmark next to them.
7. Try and scan for corruption again (run "Scan for corruption" in the Action menu). When I did this after fixing the errors I had no corruption on the disk.
8. Close down CDmage.
9. Burn the ISO back to a CD or just mount it with Daemon Tools.
10. Copy the fixed files from the CD (which was repaired) to the "core" folder where fallout tactics is installed. On my machine this is "C:\Program Files\14 Degrees East\Fallout Tactics\core".
If you're not using a full install then just try and run it with the fixed CD.
11. Run the game and see if it worked!
Prior to this fix my game was messed up at Bunker Delta. No dialog, and no speech at all.
Results of the fix:
I now get full dialog and speech, bartering, and the briefing for the first mission in Bunker Delta. Everything seems to be fine now, but I suspect that the corruption I had was largely in the MP3 files of the briefings and other dialog, so the missions themselves seem to be okay. I anticipate that some of the speech files will have some corruption in them, but I haven't encountered anything yet.
I'll continue to play and let you guys know if this was sucessful or not.
