As I said, I believe I've managed it
I've found out I really need to get more RAM for my Amiga - no games want to run from the workbench if I just set 2MB chipram with nothing else in the emulator (I still haven't received my laptop IDE --> PC IDE adaptor yet).
What I am most glad about is that I'll FINALLY be able to play Worms: DC on a real Amiga!
Oh, and is there something I need to download to open IPF disks in workbench? They all appear as DF0:CAPS and I can't double-click them.
