Today I got two additions for my Nintendo e-Reader collection:
The first one is a small piece of plastic, known as AGB-016 or 6PIN Protection Cover. It is still being sold in the Nintendo Online Shop Update: It was sold in the Nintendo Online Shop until 2014. The page can still be accessed with the WayBack Machine.
It protects the Game Boy Advance SP screen when an e-Reader+ or an e-Reader with a link cable port is plugged in. Actually, it is a very useful little accessory with the only drawback that it has to be fixed permanently on the e-Reader. The e-Reader then won’t fit anymore in the original Game Boy Advance.
