I can't install BGT-WeiDU. I keep getting a fatal error: unable to find Dialog.TLK in dialog.tlk.
I'm not really sure about what went wrong there. So you installed BG1, BG2, and the BG2 fixpack? Did you extract BGT to your BG2 directory? The BGT setup program needs to be in the same directory as BGMain.exe
Is there a way to fix the font size, like in Planescape Torment? My monitor's resolution is 1680x1050 and it's hard to read anything. PST had a mod/hack to change font size. Is there anything similar for BG2?
You can reset the resolution if you'd like, it's the only way to my knowledge. Just run setup-widescreen.exe again, and choose to reinstall. Try these following resolutions: 1440×900 or 1280x800. The graphics won't be as sharp afterward, but everything should be larger.
