It's time again to defend the honor of the System Software engineers.  :-)

Everytime this question is asked, someone comes up with the same message,
which gives the proper patches for the wrong reasons.  The problem is that
RISK assumes that the product of the screen width and the row bytes will be
less than 32767.  (It sign extends the product.)  On a Mac II that's not
the case.  GetWMgrPort returns the same thing on a Mac II as on other Macs.

Also, it is not necessary to apply a different patch depending on your
screen depth.  RISK doesn't use color, so it only needs a 2-bit deep
offscreen buffer the size of the original Mac screen.  So you might as well
apply the 2 color patch to save heap space.
