Playstation 2: LEGO Star Wars: The Video Game Cheats

In vehicular missions (particularly the pod race), the player needs to smash and destroy all the destructable objects to gain money. The invulnerability cheat ($1,000,000 in the shop) can help you get a full Jedi bar in most of the non-vehicular stages.

LEGO Star Wars: The Video Game Hint: Cheese-Kill Anakin Skywalker
In stage 3-6, have a second player take control of the boss and force the character to jump over the lava pit. Just before Anakin Skywalker hits the lava, have the second player hit pause and drop out of the game, resulting in the AI taking a hit. Keep repeating the process and you can force an easy win. Pun intended.

LEGO Star Wars: The Video Game Hint: Switch Hitting
Freeplay (or Free Mode) is best for exploring previously cleared stages for studs and minikit parts. A preset "cast" is selected for a particular stage or mission which allows a player to access all the doors previously missed in Story Mode. Use the L or R keys to cycle through the cast while playing on free mode.

LEGO Star Wars: The Video Game Hint: Begging At Dexters
Dexter's Diner, where you select your stage/missions is a veritable loot heaven. Your characters never lose money if they die at Dexter's Diner, so each time you complete a stage, walk around the place with any Jedi character and force pull studs from all the objects around the hub level.

LEGO Star Wars: The Video Game Hint: Gimme My Credits
When starting the game it is best to save all your money for the invincibility cheat, however reaching 1,000,000 coins is difficult. I found that the fastest way to collect coins is in level 5 of episode III, "Darth Vader". At the very begining of this level, you have to run down a corridor while the floor crumbles under you. If you happen to fall in the lava you simply start at the begining of the hall again. The cool thing is that you do not lose your coins. You can run down this hall over and over again, getting around 4,000 coins each time and then just dying at the end of the hall. It took me about 30 min. to reach 250,000 coins.
