That's right because I added it (which was slightly altered by JKing). And it was mentioned in that link I gave you, an equal variant was.
I don't mean to sound ungrateful for the help, I really am appreciative, but I couldn't open the files from the download you linked to, and, on the forums, I couldn't find any Mac specific directions on how to edit the DOSbox configurations without having a start window. Like I said earlier, I'm sure it has been mentioned somewhere on the forums, but I never could find it.
edit:going back, now I see where you mentioned it, and actually I noticed it yesterday when all my trouble began, but when I tried it then, it didn't work, probably because some of my earlier newb mistakes that I have subsequently forgotten about.
Again, thanks for the help. You (Mr. Oblivion) and Taemos in particular have been very helpful, and I wouldn't have figured anything out without your help. But there are little things, like how to edit the DOSbox configurations, or the fact that on a mac you need to use " ~/" instead of "c:\" that probably are considered so basic by anyone who knows anything about DOS, that no one the forums thought to point them out to me. It took trial and error, looking at various instructions sets, some which use c:\ and some that use ~/ for me to figure out why none of my early attempts seemed to get me anywhere.
