Hmm, i didn't install the Widescreen Mod. I just installed the GOG-version of BG1 and tried to start it.
I tried the "Full Screen=0" option in the "baldur.ini" but that didn't have any effect. I still got the error-message.
Is there a way to change the resolution of the game via "baldur.ini"?
There is no way to change the resolution in BG1 without the Widescreen mod, assuming you don't use TuTu or BGT. You aren't running the game in some sort of XP Virtual Machine, by any chance, are you?
You could also try posting your baldur.ini here to see if anybody can spot anything untoward.
Nope, no virtual machine. Just a fresh GOG-installation on Windows 8 64Bit.
Now i got the windowed mode working! This is weird, there are two
"Program Option" sections in the baldur.ini.
You have to put "Full Screen=0" in the first
section. The game starts at least, but in a tiny 640x480 window. But it's playable, yay :)
Try going into your BG1 directory & running setup-ddrawfix.exe & select U for uninstall.
Can't find "setup-ddrawfix.exe" in the BG1-dir or subfolder. It is a "fresh" GOG-Installation now, changed nothing.
In windowed mode i tried several graphics options, but when i select "full screen" and hit "done" game crashes with the mentioned error :-\
