The version of Karateka I have doesn't work on the IIgs unless you use
a Disk ][ controller card in slot 6.  If you use the IIgs's built-in
disk port, the game crashes when you boot it.

This happens because Karateka does all of its disk accesses by copying
the Disk ][ ROM into RAM and patching the copy.  There are enough
differences in the IIgs slot 6 ROM code to make it crash.
