Thanks for the reply.
Its not very difficult to 'acquire' anything from the net these days, if you see my point of view.
To prove just how n00b I have been, it seems that using any CloneCD version less than 4 will not correctly produce a DC CD-ROM.
It only took me 4 coasters to work this one out, could've been a lot worst.
As a footnote, I went into the city today (big city in the UK too) and scanned the second hand shops for DC games. I was amazed to find the games that I wanted, were still selling for £12-20 each! I thought this was a legacy console, looks like ebay is gonna have to take a beating
