basic emulation questions

Hey everybody, I'm new here and I have some questions about how to get isos to work. So far I have the file that I need to use yahoo sauger to get to work. When I try to load it every file always says bandwith exceded plz try again. Could that be a problem caused by a firewall, or are the files I need to get not there any more, or will the bandwith not be exceeded eventually. That has happened with two different files I tried. Also what is the torrent stuff. I downloaded bit torrent ++ and I don't know how to use it.
If anyone wants to be really nice and send me the isos, I'm looking for Xenogears. I don't know how to make isos from the cds, but once I figure it out I can offer these for trade:
Ace Combat 2
Ace Combat 3
Resident Evil 2
Bust-a-move 4
Gran Turismo 2

thanks

I think I asked too soon. I was able to get the torrent thing working, eventhough its going really slow (estimated 6 days to download one thing).

You will get more responses if you post in the Trading Post.

I don't think Yahoo Sauger works anymore.

Edit: There are a couple people who have FTPs in the Trading Post but you'll have to upload some of your games to get some of theirs.
