I know a bit about the problem. I have a 500 Mhz iMac CDR with 192 Ram.
When you try to launch Pandora with VM on you just get an error, but if you turn Virtual Memory off, Pandora will launch without problem. You may use Pandora to give your character a lot of HP and freeze the value, so when you fight the sea giants, they hit you but you always recover from your wounds, without any potions.
Hope it will give you some opportunities to end the game.
