On the ram chips in a n64, there are 4 pins coming out of the back of it.(oppisite to the side with most pins) are these ground or something else? I don't wanna destroy any ram by connecting 2 things that shouldn't connect with my multimeter.(somehow happened to my psone) if it's ground, is it necessary to connect, or can I just desolder it/bend down the ram on the exp pack a bit/trim the exp pack a bunch more than normal so no relocation is needed?
