Hacked objects in Sims 1[]
Hacked objects in TS1 were objects that were hacked in such a way that they could modify Sim character traits, Sim relationships, or Sim moods just by having a Sim use them, or added other functionality that a cloned or recolored object would not have. Some hacked objects even came with their own new animations. In Sims 1, the hacked functionality of the object was built into the object .iff file itself, though sometimes coming with separate animation files or skin files.
Hacked objects in Sims 2[]
Hacked objects in Sims 2 were not just changed in appearance, but also had added functionality. Like Sims 1, .sims2package files and .package files often contained the hacks. Mod the Sims categorizes these files as Object Mods.
