Thanks for the response, but WHDload really isn't the problem at present.
This is a screenprint of my Rom folder.
As you can see, it has many different ROM file formats within, but only the DMS files are recognised by WinUAE (and one ADF).
Can these be converted, allowing them to be recognised?
I hope this paints a clearer picture.
PS. Strange, but when I actually 'ADF'd to disk' with one of my 1.3kick roms it unpacked to present me with, from what I can remember was Amercian Lambourgini Challenge!
