Haha, those appear to be the same files that I looked through before buying Swap Magic.
Also, If you dont have a gameshark already, I would get swap magic instead because it is designed to play backups and the gameshark isnt. I have been through it all. Trust me. Before buying swap magic I tried action replay. I tried Gameshark. I even tried the psx swap trick with ps2 games. Also in changing discs I would not recommend using a plastic knife. Take a memorex cd. (has to be memorex) and cut it out to fit this diagram
May be a bit small but a thumbnail from google is all I could get. You should be able to get the gist of it.
