Just out of interest, on an expanded Amiga (say a 68030 or better), would Amiga-UAE for the classic be able to run ADF files as if they were real floppies at 68000 or 68020 speeds?
I assume that the emulation would still be quite fast as things like the processor and the custom chips can be accessed without resorting to emulation.
I've downloaded Amiga-UAE, but I'm stuck at work for the next 10 days and can't test it on one of my real classic Amigas.
