When you start out, you will see a bar with a barman behind it. Walk up to the bar and you will find a menu. There will be characters, extras, hints, and codes. Before you complete the first chapter, the characters section will be unavailable. I have a list of characters later in the guide.
The extras will be daisy chains, tow death star, fertilizer, chewbacca carrying c-3po, use old save, and all of the power bricks (explained later in the guide).
Use old save is explained later in the guide. Fertilizer makes dewbacks and banthas poop. Tow death star makes a certain level(Episode V chapter I) easier to beat. You will find bombs to lug around. Tow death star allows no enemy except AT-ATs blow up the bombs.
Daisy chains makes grappling hooks daisy chains. Chewbacca carryingC-3P0 makes it so that whenever you have Chewbacca, C-3P0 appears on his back. The codes are cheat codes that you can enter off various web sites. The hints cost very little or are free, so buy them whenever you can! Some are horrible and some are useful.
Note: To get cheat codes, you can use google, go to reg.lucasarts.com, or go to game faqs.com.
