Star Wars Battle Front Help

Okay. For Star Wars Battle Front #1 (for playstation 2)
In "Historic Campaign," (in single player) when you are selecting planets, press square, circle, square, circle and then you can scroll through all of the planets.
In "Historic campaign," (in single player) and when you are on the planet selection, press square, triangle, square, triangle, and you can unlock all maps and historic campaigns.
To get short people, make a new profile and enter JUB JUB (all caps) and in action mode (don't know about campaign) and the people will be short.

For Star Wars Battle Front #2 (for playstation 2)
U,D,L,R refer to the D pad
For invincibility-pause the game and press U,U,U,L,D,D,D,L,U,U,U,L,R
For unlimited ammo-pause and press U,D,L,D,D,L,D,D,L,D,D,D,L,R
For slow-mo sounds-pause the game and press U,U,U,L,U,D,U,U,L,D,D,D,L,U,D,D,L,R
For party time jedi/wampa hit effects-pause the game press U,D,L,D,L,R
If you go to Mos Eisley on assult mode and you can play with all heros and villans (the dark side is more powerful in my opinion).
You can get jedi/sith really easy if before you go into a battle, pause and go to options and go to hero and then you can change when they arrive, by time or by point amounts, and how long it takes until you can be them.

Hope this helps
