Where can I get a better Resident evil code veronica disc1?

I have downloaded Resident Evil Code Veronica disc 1 and after I finished it and beat Tyrant and after a cut-scene everything went black,I'm expecting that there would be able to save your game and "insert disc 2", hope you can provide me some good copy of RECV Disc 1.,thanks

there is nothing wrong with our disc, it is the emulation method at fault.
