So you want to the original Sims 2 hair modified for your Sims 2 game the same way it was for Sims 3, right? Not the hair from Sims 3 converted to Sims 2, (which would be more difficult). Perhaps you could contact Bosie on GOS and ask if they'd be willing to do the same hair for Sims 2?
Yeah, basically. XD This is why I shouldn't type while half way asleep. Thanks..
