[comp.sys.mac] Activision Copy Protection - "Shanghai"

rbl@nitrex.UUCP ( Dr. Robin Lake ) (12/23/86)

I just purchased Activision's "Shanghai" after trying the demo they posted
to the Net.  It's an interesting game/solitare based on Maj-Jong tiles
stacked in a pyramid.

Unfortunately, backup of the disk is a problem.  Copy II, Version 5.2,
using Bit Copy, Keep Track Length and Synchronize Tracks options produces
a disk copy which boots, shows the Startup Screen, shows the dragon and then
boots again.  It repeats this behavior until the paperclip is applied to
the eject hole in the drive.

Inspection with Mac Tools shows two files (1K each) with the same name
(a string of boxes, which I assume indicates characters not in the font set).
Mac Tools would not copy these to the target disk.

Track 5 seems to be villanous, too.

Any hints would be appreciated.

The demo version of Shanghai, recently posted to the net, does the
unfriendly thing of rebooting your machine when it exits.

I fixed my copy by patching the word 0xA017 to 0xA9F4. This turns the _Eject
system call into _ExitToShell. So far it has not messed up my hard disk.
(Many games leave the file manager in a bad state when they exit. After
such games it is best to reboot anyway.)

Naturally, I can make no guarantees that this fix will work for you.
