I was thinking about converting the full MS-DOS so it can run under Windows 10 64-bit. I've already got DOS 1.25 done but it is completely useless because not many DOS apps were designed for it.
It is a bit challenging doing DOS 3.x and above but I think I can get it (eventually). I've got half of MS-DOS 3.30 working already and hopefully I can get everything done next week. The hardest thing is that not every DOS utility can be converted without a risk. You certainly don't want things like CHKDSK or SCANDISK running on Windows 10 64-bit with direct disk access because it can mess up your hard drive easily. Below is my fully working COMMAND.COM and you can even launch 64-bit Windows apps using it!
PM me if anybody want any specific DOS app to be converted.
Project cancelled. No more requests.
Edit: Yep done! I figured out you don't need to convert every app and the converted COMMAND.COM can handle 16-bit, 32-bit and 64-bit apps. You can also use COMMAND.COM to run Windows 10's Command Prompt or use Windows 10's Command Prompt to run COMMAND.COM which is surprising. I am now packing this up ready to share it!
The only problem now is the copyright. I don't think Microsoft still care about DOS anymore but it would be good just to confirm that I can upload the whole OS. If I can't then you can simply grab the files off your DOS 3.30 floppy or download it from the internet to a folder and replace COMMAND.COM with this one.
Project cancelled. No more downloads.
Although I know this is 100% safe if you don't do silly things, I still have to say: I am not responsible if you mess up your computer by running this unofficial DOS port to 64-bit Windows. Please don't run any disk related commands as you might end up destroying your hard drive partitions because file systems did change a lot in the last 30 years. If you have never used DOS before or don't have the basic knowledge about it, run it in a VM for the sake of your data.
