You can already put your PC games on romm and your saves. You just download the game in gog and put it in romm in the windows or Linux platform (I think there is one for mac games also). If you already have romm installed, it might be easier to use it than to have a second service installed.

Really interesting, as ever. I love the custom boxes for games and I wonder, is there a website where all shared custom boxes (for tapes, CD or original boxes) are stocked ? It would be nice to be able to find them all at a same place and print the one we like :)
