C64 Emulators

[prplottr]

I have a C64 emulator on my system and am trying to play Questron II. I am getting stuck at a point though as the game asks me to switch disks. I have no idea how to give it the second disk image without restarting the emulator. Anyone have any ideas?
I am using the VICE C64 Emulator

Buy a real C64 + the transfer cable and you can avoid your ****ty emulator.
