In the game open the console with pressing [Ctrl][Shift][C] and then type in the codes. Note that cheats are case-sensitive!

help         - Lists all the cheats in the game.
help [cheatname]      - Displays specific information about the cheat.
exit                  - Closes the cheat window.
expand                - Expands or contracts the cheat window.

moveObjects on/off:   - Removes footprint limitation for all object placement in Buy Mode and Build Mode.  Removes limitations placed on hand tool for when objects are in use, or are normally non-movable objects. Is known to cause issues with game elements, routing, hidden object generation and manipulation, etc. Note that using this cheat allows you to delete objects that normally cannot be deleted, such as Sims,  the mailbox, and the garbage can. If you delete these objects, there is no way to get them back, so be careful!

aging -on/off         - Prevents Sims from aging. This can disrupt the carefully tuned gameplay balance, and will prevent little Johnny from ever growing up, so treat this cheat with care as well.

autoPatch -on/off     - This cheat lets you re-enable notifications when there is a game update available for The Sims 2. Just turn Autopatch on and go to the Custom Content Browser (the little snowflake button on the  UCP in the neighborhood). If there's an update available you'll be asked whether you want to download it.

slowMotion [value]    - The slowMotion cheat takes one parameter: the "slowness" setting (such as slowMotion 4). This value ranges from 0 to 8 where 0 is normal speed and 8 is the slowest speed.

boolProp enablePostProcessing true/false - Enables the use of postprocessing  cheats (see below); very useful for movie making (also see below). Please note  that you must have a video card that can handle pixel shaders in order to  successfully use this cheat. If you use the cheats and you don't have pixel  shaders, the screen will most likely go partially dark, and will not come back  until you turn off enablePostProcessing. If you turn on postprocessing, and you  turn on cinematics, and a cinematic plays, you may also experience unwanted  graphical glitches.

bloom [r g  b x] (rgb is color) (x is the bloom amount) [0.0 - 1.0]  - This cheat adds a blur effect, like a sitcom flashback moment. Must have entered boolProp enablePostProcessing true for this cheat to work.

vignette [centerX centerY X] (X is the vignetteing factor) [0.0 - 1.0] - Adds a blur effect from the specified center. Using "vignette 0.5 0.5 0.5" should put some blurry bits at the edge of the screen. Vignette 0.5 0.5 1.0 is maximum edge blurryness. Must have entered boolProp enablePostProcessing true for this cheat to work.

filmGrain [val] [0.0-1.0] - This cheat makes the screen grainy. Must have entered boolProp enablePostProcessing true for this cheat to work.

letterBox [val] [0.0-0.4] - Adds a letterbox effect to the view. Must have entered boolProp enablePostProcessing true for this cheat to work.
