Okay I got the demo up and running, looks like it uses the normal .mix files so I can plug in the files from my full-version c&c95 discs, haven't tried it yet but what I'm expecting is that the game simply won't read them because the executable isn't coded to do so, then I got a second idea - that is that if I were to download the patch 1.7x for the mac version it would likley have the updated executable in the archive so I can replace the existing one, which makes me wonder if I could have just used the patch + PC mix files all along, hopefully if this isn't the case the demo contains the mac-specific files which I would need to fill in the gaps. I'll give it a go. The real test will be seeing if I can get a game going over IPX between the mac and the PC, given that nyer's TCP patch liklely won't work on the mac.
