I have what seems like a novel problem, I can't start a BG1 game from the Modified BG2 menu.
I performed these actions:
There should be 3 buttons that greet you on the first menu screen - "Baldur's Gate", "Throne of Bhaal", and "Quit Game".
Click on "Baldur's Gate".
Then click on "Single Player".
The menu that comes up after will have "New Game", "Load Game", "Back", and "New BG2 Game".
Click on "New Game" to start from Baldur's Gate 1
The game starts in the Cages with the magic experimentation dungeon, ala BG2. Not in Cadlekeep.
This is on the GOG version, with fully installed Baldur's Gate: The Original Saga and fully install Baldur's Gate II Complete.
Last, I ran BGT in the BG2 folder.
Any ideas how I can start a new BG1 game with this mod?
