The MAC is a fine platform, judging by the limited time I have spent with it. But I use a homebuilt PC for Civ II.
I don't recall which site I got my no-CD patch from, but it may have been Gamecopyworld, or maybe Hambo.
There are 4 or 5 PC "simulated CD-ROM" software programs out there. Although I have over 40 G on 3 drives, I don't have the space at the moment to mirror game CD's to my game partition, plus I don't really care about the Throne Room, the Advisors, the animated diplomacy, or the wonder movies... so teh no-CD patch is a great solution. Anytime I want to run the original program file, I still have it too, but have to go get the CD, and turn on my CD-ROMs.
The no-CD patches are legal, because all they do is modify the original .EXE file with about 5 bytes on average. A no-CD patch is not a 'free' version of Civ II, if anyone is confused on that point (you still must buy the program before you can patch it).
Also, on pager v of the manual, it tells you the multimedia files to copy... it's the contents of 2 directories. I think, however, the program will still check to the game CD when it starts, even if you copy the MM files. The no-CD patch eliminates any access to a CD.
