Way of saving MDS off a hard disk but not on cd or dvd, but dvd-ram>?



I am unable to burn Splinter Cell pandora tomorow with my sony drx-800ul, and was wondering; if I transfer the image to a ram dvd disc, would I be able to ‘store’ the MDS files there when Im finished/have got tired of the game and then just transfer the MDS files back to the hard disk of my computer? Ive tried mounting the image and it looks like I can run ‘setup’ without any problems. Any help would be appreciated.

Another question, would it be possible to mount the disc from the dvd ram disc??
The game says it reccomends needs a 16x cd-rom drive.
