How do you change lots in freeplay 2 player mode on the sims 2 for psp2?

In The Sims 2 for PSP, you can't directly change lots in Freeplay mode. Instead, you can switch to a different lot by using the "Map" feature to select a new location. Once you choose a new lot, you can start playing there with your second player. Remember that gameplay is limited compared to other versions, so customization options are minimal.
