Cheat gnome:
Pause time, then quickly press R2, L1, R1, L2, Left, Circle. A Sim voice will say 
something to confirm correct code entry. A gnome should appear near the house 
that your Sim is at. Select it for 10,000 Simoleons. 

All objects unlocked:
Enable the "Cheat gnome" code. Pause time, then quickly press L2, R2, Up, 
Triangle, L3. A Sim voice will say something to confirm correct code entry. 

All visit locations unlocked:
Enable the "Cheat gnome" code. Pause time, then quickly press R2, R3, L3, L2, R1, 
L1. A Sim voice will say something to confirm correct code entry. Note: This code 
can be entered any time after your Sim wakes up at Mom's House after the 
initial "Dream Sequence".

Boosting a low budget:
At Mom's house, Mimi's place, or Dudley's trailer, buy things until your budget 
drops below $100. Wait about an hour. When the phone rings, answer it. You will 
get free money. Repeat this as necessary. 

Raise motives:
To help raise motives in later levels, move back to Mom's house. The Artificial 
Love will make raising motives easier. 

Raising skills:
While living with Mom, do not run out and get a job after you have completed the 
first few goals. Instead, stay around awhile and use that time to build skills. Mom 
will nag you, but just select "Okay" and keep doing everything else. Make sure to 
keep yourself happy and entertain/talk/joke with Mom to keep your relationship up 
to par. When you have your skills where you want them, move out. This will make 
things much easier. You will then be able to concentrate on your job and 
relationships, rather than skill building.

Notice that when you are at your Mom's house at the beginning, your Sim's energy 
and social do not go down, and will remain at the halfway point. Using this, you 
can raise your skills faster. First, have breakfast, lunch, or dinner. Then, use the 
toilet, take a bath, watch television for fun and comfort, then finally work on 
whatever skill you want. After repeating this routine before having breakfast, 
lunch, or dinner, clean up the plates. Do not call a maid or anything else, as it is a 
waste of money. For extra money, do creative skills on your paint set and sell 
your paintings when done. This will give you a lot of money when you are done 
with your skills. Do all goals except getting a job. Do not sleep or talk to your 
mom while doing this. When done with Cooking, Mechanical, Creative, and 
Charisma, buy a chess table for Logic. When you are done with those skills, sell 
the chess set (whole refund). Then, buy the weight lifting machine for the Body. 
When done with all skills, get a job and move out.

Unlock social options:
To unlock most social options, become friends with the Sims. For example, when 
you be friends with Randy you will unlock "French Kiss" and with Paisly you could 
unlock "Spank Booty". Each Sim has there own social option to unlock when you 
become their family friend.

Jock career:
To successfully complete the Jock career, you need to have all Body points, 4 
Cooking points, and 5 Charisma points. You will also need six friends. A quick way 
to complete this is go to Mom's house and buy something to work your body (for 
example, a treadmill, pool, etc.);a bookshelf or something similar to the gourmet 
cooking stove; and something for your charisma (for example, a microphone or a 
mirror). Do that, then build your skills and move to the different houses so you 
can complete a goal and unlock something. You will eventually get to Malcolm's 
mansion.

Skipping work:
In Bustin' Out mode, you can skip work by moving back into Mom's house. While 
you live with Mom, the bus will not arrive, and you do not have to work. This is 
useful if things are not going so well and you need some time to "restore" your 
Sim.

In Bustin' Out mode, you can skip work by changing jobs before the bus arrives. 
Later, you can just change back to your old job. This is useful if you are about to 
get fired. Note: You will only get fired if you skip work two or three times in a row.

Never work:
In Bustin' Out mode, the people who you live with (who you can control) cannot 
get fired. If you want them to stay home, just let them. This can be very useful if 
you need them to clean up, or need them to do some other things.

Get a bigger room:
When at Dudley's trailer, go to the master bedroom. Then, sell the door that leads 
to the smaller room so that there is just a wall. Next, make a door at the top right 
corner so that there is a place you could walk into the smaller room. Then, 
decorate both rooms' wallpaper and carpet to be the same and you will have a 
bigger room.

Raising a baby:
When you have a baby, do not play with it ever, as it does nothing. If you feed it 
then sing, it will stop crying for a couple of hours.

Fishin' For Profit book:
To get the Fishin' For Profit book go to Nikki Nack's store (open from 9 a.m. to 5 
p.m.). After you buy it, find O'Phil Mclean. Give it to him and he will give you a job. 
Note: You must get the goals from him first. To do this, talk to Salty. Later in the 
game, you will be offered by Nikki Nack to buy the Waterfront Villa for 3,000 
Simoleons.

Throw an art opening:
When you move to Studio 8, one of the goals is to throw an art opening. In order 
for the art opening to be successful, you have to purchase a Sculpting Block and 
sculpt it first. Then, have the party and it will be successful. However, before you 
can purchase the Sculpting Block, you must complete the goal that will give you 
access to it.

Dead plants:
When a plant is dead, do not throw it away. You can sell the dead plant for as 
much as a new plant costs. 

Easy money:
When you go to a house and do not have much money, trade in all the wallpaper 
and buy the cheap version. You can get a good amount of money. You can do the 
same thing with the tile.

When you move into a house, sell all the wallpaper and tiles. Then, change the 
tiles to grass and the wallpaper to nothing. 

Instead of working, you can get a workbench from the "Building Skills" section in 
buy mode. When your Mechanical skill is at its best, you will get 100 Simoleons for 
each gnome you make. It only takes about five seconds to make each gnome, and 
you can make about thirteen gnomes at once. Note: Your Sim will only make 
gnomes when in a good mood.

To get lots of money, enter buy mode and sell the paintings. Some of them are 
worth a couple thousand Simoleons.
