ok so im probably the worst umd door remover ever i break them all the time so i was almost tempted to not even try on my new slim.but i did and couldnt do it with a screw driver from the inside i felt like i was about to break the peg before door comes off. so i started thinking how to do it i decided to stick my thumb way into the umd drive to the bottom from the top and put fingers on each side of door on the outside then i bent the umd door out to bow out away from psp and push it to the left as you bend and it will come right off the peg idk if this has been brought up just thought id share my experience this was on a white starwars slim
