If it is illegal then sorry but I don't think it is.I want to know how can I play Sims 2 on computer directly without CD??Please tell me It requires a lot of time to load with a CD.

without entering the illegal part you can always create a image of your original cd with alcohol for example.
then mount it on a virtual drive enabling all emulations.

And how is that done?

erm... using the assistant to create images... then rightclicking the virtual drive device and choosing "mount image"...

just play with the options/interface is really easy

I m sorry but how can i get this alcohol and what is this virtual drive is it my installed game folder??

sum1 plz shoot me! download "alcohol 120%" , just google it
