My ps2 has been f***ing around for too long and after several blows to its case and trying every posistion possible just to get it to load a game or dvd id even contemplated hanging it at 133.5 degress off the lampshade in the shitter. I was ready to use it as a discuss and hurl it into someone back garden, Then i found this site and it took 10 mins and now it loads anything everytime
God bless the internet
