Cheat how to get yoda ghost on Lego Star Wars?

i dont know a cheat but i can get loads of money just do the first chapter [the space one] on episode 3 and do the challenge where you have to get all the blue minikits and you get an odd 120,000 for each time you do it if you keep hold of the shoot button and you need to do it around 10-12 times [Please note it is for The Complete Saga only]
