I'm installing the mods right now. ^^
Edit:
Just finished installing BGT WeiDU and was going to install BG1 UB but:
II. INSTALLATION
Double-click the BG1UB_v9.exe file and install to your main BG1 directory
Once the install program has finished, it will launch the WeiDU installer program. Simply follow the on-screen instructions in the new DOS window.
It says to install it on BG1 folder but, since I'm using BGT, I should install on BG2 folder, right?
