* What is CivHackFAT?
CivHackFAT is a "fat" system extension (or INIT) that fixes a problem
many people have running the MicroProse's Civilization(TM) on
PCI-based PowerMacs under System 7.5.2 and on all PowerMacs under
7.5.3.  Running this extension should solve at least one class of
problems with Civ on PowerMacs.

* Why CivHackFAT?
Why indeed, since there's a CivHackPCI out there that basically does
the same thing.  The reason is technical:  CivHackPCI patches a
PowerPC-native trap with 680x0 code.  This is fine when running old
680x0 applications, but generates unnecessary (and very slow)
mode-switching when running PowerPC-native applications that like to
twiddle the color cursor (e.g. NewsWatcher).  CivHackFAT solves this
problem by applying a "fat" patch of both 680x0 and PowerPC code.
CivHackFAT also provides information about whether it loaded correctly
at startup time, which CivHackPCI does not.

CivHackFAT is free.
