Actually I found them a few days ago on Aceroms. There name is Skid Marks 2.2.1 (HD) (1995) (AGA) [cr] (Disk x of 3). It's exactly the same as the ones I bought from HMV many years ago. Just load disc one of this set and you get 3 extra championships to choose from.
Suppose I should have updated my thread but I've been having too much fun on my A1200 lately
