need help with pcsx

I know people have mixed fillings about emulators but i'm hoping someone will help me out.....i found a website were i can download roms but this site has them in different pieces for example armoredcorepart01.rar i downloaded it and extracted it but it doesn't work if for example if there are 10parts do i need all ten for it to play?

Quick answer is yes. Most times you will extract the first file which will look for the rest and extract one file. Then you will need to extract the .zip file that was just extracted from the others.

Good luck.
