I made a Qemu/DOS bundle to run my XFDOS package on Windows7/8. More or less as a proof of concept. It also includes a small FreeDOS distro called MetaDOS from Rugxulo.
You can download it here:
There is a lot of DOS software that will not run on Windows 7 or 8 in 64bit
mode. To allow DOS applications to be used on these systems they can be
bundled with DOS4WIN64 and started from the disk like any other application
on a Windows 7 or 8 system. No need to install DOSBOX or VMWare first. Or to
burn a Live CD and boot from that.
Just copy the DOS4WIN64 archive files into a directory and start the batch
file to run DOS and the DOS application from there.
So if you made software for DOS you do not want to abandon you could make a
Win8 version with DOS4WIN64.
You could also make a version of this package for Linux and OS X using a different version of Qemu thus making the DOS application "cross platform" ;-)
Without my included XFDOS ISO image this package is just about 5 MB in size.
So if you have a DJGPP application that you want to make available for Windows
7 or 8 in 64 bit mode you could add this to the MetaDOS image in this
package and allow your users to run it on Windows 7 or 8 without installing
any additional emulation packages. If there is a FAT disk available on the PC, this disk can be accessed directly if configured.
