@The_Picard_Maneuver I had most of this monstrosity! No Action Replay because the Game Genie was enough, and no bottom set of speakers because the side speakers were enough. Not visible was the big heavy rechargable nicad battery that clipped onto the back.
I also had a backup device, that only backed up the battery backed save data not the whole ROM. But it was useful for overwriting the save data from Pokemon Red over Blue, catching some Blue-exclusive mons, then writing the save data back onto Red. It had the same form factor as the AR shown.
@The_Picard_Maneuver Oh and I remember those two little tabs on the top of the magnifying glass part were for a neck strap, as all these attachments nearly doubled the machine’s weight and made it really top-heavy. The strap was to help you hold its overall weight.
