My ps1 started having troubles playing burnt games. it's a psone mini. It goes to the madia not supported. It used to work every time. now it takes a bunch of times to boot up. sometimes i get lucky and it just boots up. Im wondering if tweeking the pot would fix my problem. I seen a video about tweeking the pot for the big ps1 to fix some the problems. Or is the mm3 chip going bad? I got from a good ebay seller. i think there is warranty but id prob have to pay for shipping. I gotta pick up a muiltimeter thou. i haven't used one before but ill try to figure it out. i took electrical before in high school so i know a little. what is the increments to tweet it each time?
