Seems like a nice trick to have in the hat :), though right now I haven't a practical use for it:

DOS File substitution

This is a very specialistic tool, designed to work only in DOS/DOSBox. It intercepts requests to open a file and reroutes them as specified. For instance, your game might try to get its configuration from a file called RESOURCE.CFG, but you want it to read from MT32.CFG instead. If so, just run the command "fsubst resource.cfg mt32.cfg" before starting your game. I wrote this program for just that purpose: to switch configuration files for games stored on a read-only medium.
