The reason I wanted to use DosBox is so that I could try to link up with the DOS machines on our network that we host games on occasionally. (does this work? I haven't tried yet, just curious)
I solved the problem, and it didn't have anything to do with the patches (that's a whole different problem all together.)
It involved mounting D: as a CD drive. Apparently I had to differentiate. I checked it out online before, but apparently overlooked it. The game version I have requires the disc to be in the drive. It's version 1.4 that shipped on CD. It's the "parental locked" version -- this is probably why the patches were not working, so I had to mess with it in a few other ways.
I'd also like to let you know that on my Intel Core 2 Duo @2.4gHz machine with DosBox 0.70, this game is running properly and at full speed at 640x480 😀
