We're well aware of a commercial project aiming to achieve that goal. Originally, actually, that was scheduled to release today. That didn't happen, unfortunately, but that does give us a great reason to tell you how to make your own enhanced edition of Baldur's Gate. It's very nearly hassle-free and (especially with the sale going on) it won't cost you much at all. There's one catch, though: you need copies of both Baldur's Gate and Baldur's Gate 2 in order to enhance your game. Let's see how! One of our users, GoJays2025, committed his time to write a comprehensive guide on the topic. We know not all of you dare to venture into our forums, so we thought that sharing this guide here, might be a good idea!
So, are you ready to enhance your GOG.com edition of Baldur's Gate saga and play both games as one, seamless adventure with the visually superior BG2 version of the engine and its updated mechanics, and with high-res graphics better suited for your modern wide-screen display? Here's how you do it, according to GoJays2025!
1. Fully install Baldur's Gate: The Original Saga
2. Fully install Baldur's Gate II Complete.
3. Download Baldur's Gate II Fixpack (Download links are on the left side) and extract it to your Baldur's Gate II directory.
4. Run the newly extracted setup-bg2fixpack.exe (if not automatically started).
5. It is safe to select yes for all the optional fixes, but if you want to learn about each in detail, consult the readme file that comes with the fixpack.
6. Download BGT-WeiDU and extract it in your Baldur's Gate II directory.
7. Run the newly extracted Setup-BGT.exe and follow the instructions. You may need to run it in administrative mode in Windows Vista/7.
8. Enter Baldur's Gate I's directory when asked (if not already provided)
9. Wait for BGT-WeiDU to finish installing.
10. OPTIONAL: Download and install Baldur's Gate 1 Unfinished Business as well as BG 2 Unfinished Business. These mods restore things that were previously cut from the released product, so while you don't need them, and they do add new content, they're pretty nice to have, especially if this is not your first time.
11. OPTIONAL: Download and install any user-created material (banter packs, expansion mods, new NPCs, etc.)
12. Go to your Baldur's Gate II directory, then find and run the file Setup-BGTMusic.exe and select 'Hybrid Baldur’s Gate/Shadows of Amn/Throne of Bhaal music'. This makes it possible to hear the original Baldur's Gate music when playing Baldur's Gate I.
13. OPTIONAL: (for more experienced users) Download Baldur's Gate II Tweak Pack (if this link doesn't work, please try the emergency mirror site) and apply it in the same way as the fixpack. Consult the readme file for details of each tweak - too many to list here. If you don't know what a tweak does even after consulting the readme, just skip it.
14. OPTIONAL: Download and install the Bigger Fonts for BGII mod if you plan to play in really high-res and don't want to strain your eyes reading tiny text.
15. Download the widescreen mod and apply it in the same manner as the fixpack. This makes it possible to play the game in high resolutions and in widescreen format.
16. Remove the Baldur's Gate I installation if you wish - it's done its job!
Now you should be able to play the game all the way from Baldur's Gate I to the end of Throne of Bhaal in one continuous game! Enjoy!
Note: If you're on Windows 7 you might want to install the games in a directory other than C:Program Files or C:Program Files (x86) to avoid potential problems. C:Games should work.
