A nice alternative to the InSim mod can be found at Simbology.

It's called the Sim Blender, and does 99.9% of everything that InSim did.
You might want to check it out! (TwoJeffs- the Simbology site owner- has a lot of very cool hacks/mods you may want, including an AL/M&G compatible version of InTeen, if you are an InTeen addict, like me!)
