There is only ONE mini image on GameCopyWorld Site and that image is for the original RTW.

I've heard that RTW:BI has some special protection on it that prevents a mini image from being made. Looks like the only option you have is to use the 1.6 no-cd fixed exe or play with the original. Not sure that it is impossible to make a mini image for BI, but even if it does use Safedisc 4, conventianal mini image making doesn't cut it for this one. I doubt we will ever see a mini image.
