I used Slysoft CloneCD as well as Alcohol120% to write and backup an ISO of Harry Potter And The Order Of The Phoenix for PS2. However, when I get to the main "Press Start" screen, nothing happens when I hit start. I hear a snippet of music, but nothing else.
My PS2 is quite old and has recently been serviced to try lengthen the life of the laser, but all my other games are working fine. I used Verbatim -R.
