Hello.
I'd got the same problem with Wiskey Bob, but I haven't anymore. It was when I was trying to find best non-default scaler for me. I was trying one after another, but all of them was either slow, ugly or both. And all of them caused problems in Klamath, black screens or game freeze. Then, after setting scaler to default, problems vanished. And it works fast and smooth, also.
So, bonczyk & michi, did you change something in ddraw.ini? My problems occured only after I changed some graphic options, default scaler works just fine.
And just for the record, I am using Win7 64-bit, Fallout 1.00 US and Nirran's MM Installer.
Best regards,
/Yg
PS. Now I found that I however have similar problem. My game is failing when I end conversaton with Bob directly after he give me booze. But, if I ask him about anything after he give me drink, I can exit dialog without any errors.
Edit: Here is another part of bugs:
1) It seems that B-Team mod (NPC changing armor) does not working anymore. At least with Leather Armor or Combat Leather Armor, and both Vic and Sulik. I do some further testing when I find more armors and/or more NPCs.
2) Lara quest in Den is bugged. Just after resolving party fight in Residental, Lara says that they are going to church (and they actually going there), got XP, level, whatever. Then in a few seconds game freezes.
Renaming hs_ondeath.int solved the problem - game does not freeze nor crash after fight.
3) Klint refuses tu put down the spear after he equips it.
4) Starting FO2 directly from game folder seems irrelevant, bugs and freezez still appears in the same places as before.
5) Moving dlls (other than ddraw) also seems irrelevant.
