How do you make ISO's of real PSX games?

I bought xenogears and it sucks coz my first disc does'nt work so i downloaded the first disc and im preety sure that my second disc works...i dont wanna dowload such a huge file for 2nd cd... how do i make the .bin/.cue's
or ISO's?

You need to use a program such as Nero or Alochol 120% to create images. Look around on Google and you'll find trial editions of them. Also, just so you know, you can use Daemon-tools to mount the image files, although epsxe can read ost image files anyway.

Or do a forum search, since this has been asked over a 100 times already...

Use magic iso, its not free but you can make isos from the cd rom or change it to bin/cue from other formats and is quite simple.
