I have heard that it is only the cracked version of Karateka which has
a problem.

The problem is that on every disk access, Karateka takes a copy of the
ROM from the Disk II controller card and patches it.  It then uses the
patched copy to do the disk I/O.  The resulting code crashes on the
IIc and IIgs because the routines in the firmware are in a slightly
different location.
