MGS PSX epsxe issue

[laozing]

I am playing Metal Gear Solid disc one and I reached to the part to where the game says put on disc two.
How do I continue playing?

After you save like a real sony psx.. Then just eject it then insert cd two in it or unmount it with a daemon tool and mount next 2 and you are good to go. :)

Forgot to put this: Psycho mantis. How do you switch the controller to fight him?
I have been trying to crack that one but cant....
