The DR-DOS/OpenDOS Enhancement Project

I am using Windows 7 64-bit. If it comes to that point though I'll just set up a physical development machine - I have plenty - I just like the simplicity of DOSBox because you can mount local directories as drive letters, it's more convenient than a VM. As well, now that I think of it, installing proper DOS on DOSBox breaks that functionality too, so I think I'll just use a physical devbox.
