Sims 2 Cheat Codes

Firstly, bring up the cheat console by pressing CTL + Shift + C at the same time. Then you can enter any of the following codes for the corresponding effect:

Display and Performance
autopatch (on/off) - lets you know if theres a patch available
StretchSkeleton makes your sims larger or smaller
TerrainType (desert/temperate) - Switches between the two terrain types
vsync (on/off) - increases game performance but lowers graphics

Just enter 'exit' to close the cheat console. You can also enter 'expand' or 'contract' to make the cheat console bigger or smaller. You can also enter 'help -all' to get a list of all cheats!

It's probably obvious, but for the stuff in brackets just write one or the other! So for example if you want to switch on the autopatch function, just bring up the cheat console, and enter: autopatch on, and to turn it off enter: autopatch off.
