Dark Castles, like many animation games, uses the alternate screen buffer.
There are two ways to install memory-resident tasks on the Mac.
Put it in the system heap (discouraged for the pre-Mac Plus; later
machines have larger system heaps) or steal it from high memory.

Unfortunately, stealing it from high memory prevents one from ever
having an alternate screen buffer.

Somewhere there's a PD program that pre-allocates the alternate screen
buffer (so it will be there later) BEFORE other programs steal the
memory.

If not, it's easy enough to do -- just write a program that sets
the appropriate _Launch parameter before calling your program.
