Report Software Issue Loading Dark Castle in Mac II, Quadra & Centris Posted Friday at 07:27 PM Please if you can show us a screen shot of the error. Likely, it is the usual error message about memory allocation. First, DC/BDC were designed to play on the 68000 and the were written in assembly language. They use a minimal, custom System file to boot the machine and run (usually). Using other systems is haphazard and can create memory address issues, especially machines that run in 32-bit mode with more than 8 MB RAM. The only way I know to reliably fix this is to play the game on original 68000 hardware that can run the custom System file that DC/BDC came with. It is likely that System file is a derivative of System 4 if memory serves, and that will not run on an LCII or IIsi. You must be using it with another System file. Alternatively, you can try and have DC start the way it was intended: with no Finder. Set startup with the DC application set to open via the Special menu (if you need instructions, we can help). You can give that a go.
