- Shadows of Amn only (i.e. no patch)
- Shadows of Amn + official patch
- Throne of Bhaal + official patch (again)
None of these resulted in MIT's controls becoming available. Between the patched SoA and the patched ToB, I decided to try copy-and-pasting the path to my BG1 install (MIT did recognize this install before) into the "Source" line to see if the controls become available when that happens (they did).
