I have sims3showtime and don't know any cheats specific to this game. I'll just tell you the general cheats. Click ctrl shift c all at once and code bar pop up at the top of your screen. Type in testingcheatsenabled true .It's important that you leave a space between enabled and true. Then you can shift click on the ground, your sim, an object, and then cool options pop up. Their are other codes you can type in the code bar thing. Actually, there is one cheat I know for the acrobats, singers, etc. in sims showtime. If you type in testingcheatsenabled true and touch the experience bar for the acrobat or whatever you can give them more experience. All you have to do is click, hold, and move the bar and they get experience.
