Do you know fakecd, CD-SPACE, or Daemon Tools?

‌Officer...
You can go ahead and arrest everyone who clicked on this post~~~
Just kidding..
Back in the early days of DOS and Windows, I used to play games by using fakecd..
to trick the computer into thinking I had a CD inserted...
Back then, it was the era of DOS, so we had to manually type out all the commands and directories,
but things got a bit easier starting from CD-SPACE when the Windows icon era arrived...
