NEED A WALKTHROUGH

So I downloaded PSO ep I and II using the links on this site, and after the two hour download for this game I was excited for, I'm having trouble figuring out how to get the iso to play the game on the emulator? It's just a bunch of "winrar archive" files that don't change no matter how many times I extract them. I'm new to this so I might be doing something wrong. HALP

Just extract the first part of the archive and you should get the .gcm or .iso file after it's done. But, if that doesn't work, try using 7zip instead.

Post a screenshot of the archive files if you still having problem with it.
