BMX Bandits? I could swear it was bmx bandits but that site says racers, i do remember the screenshot on the back though, which i coveted but didnt have the money to buy.
I actually still remember the day that the local papershop started selling mastertronic games, we couldnt believe that we could buy games for £1.99, it seemed insane, we clubbed together what we had and bought Psycho Shopper I think it was, for my mates Vic 20 which was the best game we had seen on it at the time.
Good memories, i do remember buying a Cadbury's Caramel at the same time, the only and only time ive ever had it, after seeing the advert with the rabbit and getting a bit turned on by it (as a 9 or 10 year old).
