Works great in OS9, however in OSX it requires the OSX Carbon patch and image to be mounted.

The patch is at the following adress:;sa=view;down=10

However, after examining what the original no-cd crack for OS9 does (using windiff), here are the hex values to change to play WITHOUT having the disk image mounted.

Open your favorite hex editor (hexfiend is a good one), and open SMAC Carbon (from the above patch)

go to offset 0c030


82 00 0c 38 60 00 00 48


82 00 0c 38 60 00 01 48

and this should work like a charm without the disk image, exactly like when using the old no cd patch in OS9!!

Brilliant game a nice addition to Alpha Centuri; as far as I can find though there is no 'No CD' patch so remember to keep the DMG for it to work.

Runs fine in Classic under 10.4
