I think my USBMOD installation (one wire) change the way that the laser read before. It cannot read any PS2 backup anymore with my no-solder mod. Many nomod games I have before is not working with USBMOD. So I am planning to adjust the laser len to see whether I can get my nosolder mod work again. Are there anyone know how to adjust? I found many pics to show you how on the web but I cannot find anything for V5. I want to know which one is for CD so I won't mess up with the DVD one. Thanks.
