I used the left side board. One that has ps button. Just had to use the 3G back plastic because a metal prong was in the way and I didn’t want to clip it off the board. The right side one idk if has any raised spots on it. Maybe just a a little pin for the 3G chips wires to clip onto it. I needed a ps button side cause my joystick leaked fluid and screwed up that side. Ps button light would flicker and stay off and loss function of buttons. Think the liquid was joystick lubricant and it left film over contacts so caused issues so bought broken screen 3g vita cheap and swapped the board and just used the back plate. But it works fine in my reg 1000 vita
