So i have a PAL slimline PS2 with a matrix infinity chip installed and a laser fix. My PS2 DVD and CD games work absolutely fine but my PS1 games boot up but skip all over the shop. I have the same issue with music CDs. All games used are the original versions and not back ups. Could someone advise me what the problem could be and how to fix it please? I'm thinking i might just need to realign the laser but don't know how to. Thanks.
