When I mount c:\ as C in DOSBox, it gives me a message "you shouldn't do this, use a subdirectory next time". This post gives an example why this may be a very useful thing to do anyway:
I have two PCs, on both of which is running and old, but very good DOS graphics program which uses DOS full screen mode. This program itself reads/writes files from a number of directories (part of which are set by environment variables), uses batch files with absolute path definitions, and furthermore reads/writes data files from still other directories. I use an automatic system that updates such files on one PC when they are changed on the other.
One of the PCs has a graphics card that does not support VESA, so full screen DOS graphics works *only* with DOSBox on that PC (and thankfully, it works pretty fine!).
If I would need to specify anything else but c:\ as the C root in DOSBox, there would thus be different directory trees on the two PCs, and updating files would be a mess, and there would need to be two different sets of batch files with different path specifications.
Thus, if you want to use DOSBox just as a replacement for the "normal" DOS window, you sure want to mount c:\ as C, d:\ as D, etc.
I think this is a great project, just it should not *only* focus on making games running (which is of course great, too), but also be thought as a general DOS substitute, as the number of new computers that doesn't support DOS anymore fully (like e.g. with the graphics) is unfortunately increasing.
