I'm not sure if it's like the same thing as your's dropout14, but this is what happens to me:

When i go into SP, i see a PS2 controller. Like the layout of the controller, i see it right in front of my eyes and imagine myself pressing the "select" and "start" buttons at the same time to reset myself and get out of SP. If it doesn't work i feel like i'm stuck and can't get out for ages.
