The UK edition came with a manual and a precautions booklet. Except for the second German edition, all PAL editions came with the same discs.
There is another British edition with a smaller Capcom logo and no "2 Discs" text on the front. I have also seen a cover with a normal, big Capcom logo without the "2 Discs" text, but that may just have been pre-release art and not an actual scan.
