Can somebody tell me why some Starforce
 

games just need a no-cd or dvd crack, but others need some ellaborate scheme of diabling things and unplugging drives on top of an image file?

I guess what I am asking is if it is possible to remove Starforce somehow from my end, so all I need is the no-cd/dvd executable.

There's easy-to-crack versions of Starforce (shallow, cheap) and hard-to-crack (deeply embedded, expensive to buy/license). See other threads (SEARCH button) for more details.
