The only changes are:
-removal of the Windows NT lockout for versions 5.0 and greater (e.g.,
Win2K)
-a fix to the sound mixing subsystem, which may also help with Windows XP.
This patch has not been tested on more than a few machines, has no
installer, has not been approved or tested by Sierra On-Line, is AS IS, do
not operate heavy machinery while using this patch, etc, etc. It worked on
a Dual P3-1000 with a GeForce 2 GTS running Win2K SP1; your mileage may
vary.
We've also had a report about incompatibility with Win2K SP2 but have not
been able to reproduce this in house until we upgrade to SP2 ourselves. If
you're running a flavor of Win95/98, there's probably no reason to use this
patch unless you're having sound problems.
