Game guide:Changing names

Many times in The Sims series, players will end up wanting to change their Sims' names. Maybe they spelled it wrong, maybe they changed their mind, maybe they married someone with a weird name. Here is a tutorial on how to change an unwanted name.

Changing First Names

 * 1) Download the FFS Lot Debugger and place it onto the lot.
 * 2) Select the Sim to be renamed.
 * 3) Open the console menu by pressing CTRL + SHIFT + C.
 * 4) Type in "boolProp testingCheatsEnabled true" without the quotes.
 * 5) Hold SHIFT and click on the debugger.
 * 6) Click on "Rename Me", and then on "Change First Name - Cancel Error".
 * 7) An error dialog will pop up. Click on "Cancel".
 * 8) The dialog used to name a baby will appear. Change the Sim's first name as you see fit.
 * 9) Hit "OK".

Changing Last Names

 * This way of changing names requires SimPE.
 * 1) Open SimPE.
 * 2) Click "Neighborhood Browser," and choose the neighborhood the Sim you want to rename lives in.
 * 3) After the files open up, click on "Sim Browser," and look for that Sim.
 * 4) After the Sim files open up, look at the two text boxes in the plugin view. The first one is the Sim's first name, and the second is their last name.
 * 5) Click on the second text box and change it to the name you prefer.
 * 6) Click the "Commit" button.
 * 7) Save.

Brain Enhancing Machine
This method requires University Life. A level 3 brain enhancing machine or the pro brain enhancing machine has the ability to change a Sim's personality. This will allow Sims to change their traits as well as their names. Be careful though, as personality programming can fail and randomize the Sim's traits, and may possibly burn them if they're singed.

By cheating
As of patch 1.22, players can use  cheat and shift+click the target Sim to access the CAS menu by using the "Edit in CAS" option. This will send Sims to CAS, and the players are able to modify Sims. This method might cause some glitches, however. It might reset Sim's age. Also, be wary not to be tempted to make any drastic changes like Sim's supernatural type, as it will not properly change the Sim's state.
