(re: Running older games)
You need a file called mouse.com in your DOS directory. You may already have that file on your computer, take a look. If you do, you need to edit your autoexec file (use Notepad) — add this line:
I think (but am not sure) you could also get it working by typing ‘run MOUSE.COM’ from a DOS prompt.
If you don’t already have mouse.com in your DOS file, you can find it online, or I can upload it here later (I had to do this on my own computer).
