Help with Toy Story 2 ps1

Hi, I just downloaded this game. (first game I have downloaded from here) I think it says it was in some type of file called .rar . How do I convert this file to where I can play the game? (I have Windows Vista if that helps)

You have to have Winrar.

www.win-rar.com/
After you download it extract it then you get you game file.

I used Winrar to extract the file an it gave me a type of file called .bin . My computer can not play this type of file. How can I convert it again to a type of file that I can play on Vista.

I read that you have to rename .bin to .cdz. Try it.

I tried changing it to .cdz but it didn't work.

To play PS1 games on pc, you need to use PSX emulators.
ePSXe is recommended, follow this tutorial if you're new to this.
