Have you ever had games and lost the manual or boxart? Do you wish you could have them or look at them again? I'm sure that the answer for 100% (yes I will assume that much =D) of you will be an enthusiastic "YES".
Well, the site I'm providing won't get you a physical copy of either, BUT it is a database that holds nice electronic scans of them. I've already spent an hour perusing the lost manuals of old games I have.
Games Database - Online Games System Repository
It has systems from Atari 2600 to the last round of consoles. Apologies in advance if you waste too much time on this like I surely will =P.
*ADDENDUM*
BTW this collection is NOT complete by any means. So your game manual/box may not be there. If you happen to have a missing item you should find a way to contribute =).
