I had no problem installing this package into Delphi 12 as the compiler directives appear to be of the {$IF CompilerVersion >= variety which do not require modification. The only problem I had was in using SVG images, which I pushed a patch for (#114), but that problem is not a Delphi 12 issue. For the main tb2k*12.dpk files, I just loaded the 11 versions into D12 and saved them as 12, then compiled / installed.
