I have just uploaded a video with some tips on youtube:
The tips I go through are:
Set you lives to 5 obviously.
Set you score limit to 10,000 so that you get a life every 10k points you get.
Keep going in and out of the screen changer (not sure if this is the right word see vid for more description) until the ghosts have all spawned.
Get the top right pellet first because it is the hardest to eat all four ghosts with then the top left one and then either of the bottom ones.
It's better to lose a life then go for it when you are unsure.
Keep persevering with it and you'll get it.
