i would like to put the emulator into the amiga like this:

So the buttons are not accessable for me and I have to use the "file selector" (bootloader).
Is it possible to use a 2-disc-game?
How can i assign disc 1 into drive 0 (slot 0?) and disc 2 into drive 2 (slot 1?)?
Is there a way to save those settings that i don't have to adjust this everytime?
Thanks,
NBG
