how to switch discs with resident evil

[dwg14]

So I have Resident Evil and I saved right before the Lisa Trevor fight but when the game asks me to switch discs I have no idea what to do!

I guess all multiple disc games will suffer from the same problem, is there a way to switch discs?

Of course there is a way to change discs, you just gotta look for it. At the top of the Dolphin GUI, File ---> Change Disc.
