Hello there, i would like to preface this message with the statement that i have no idea what i am doing. i am an absolute noob who more through luck than skill has managed to get this far, however with that out of the way i will continue with my question.
I have installed ROTWK and gotten it working perfectly. it works fine with the 2.02 patch. 
However.
I would like to use the Edain mod with this game, however to do that i must use the mini image mounted to an scsi. however i have no earthly clue how to do this and demon tools scares me due to the horror stories i have received from friends about this, a guide to inform me on what to do would be very much appreciated. 
Thank you
