The Magic Roundabout was a tie-in with the TV show of the same name, CRL published the Spectrum version and were working on a C64 version (As mentioned in an issue of Your Commodore). The spectrum version can be found here: http://www.worldofspectrum.org/infoseekid.cgi?id=0002985
The game itself was a simple collect them up and received average reviews.
We are not 100% sure of what happened to the C64 conversion though. According to the ex-head of CRL, Clement Chambers, it is thought that not much was done on the C64 version due to it not being able to handle the scrolling used in the game. We will need clarification of this from the developers to be sure though.
Jay Derrett had thought that the game was actually completed and believes that he transcribed the music. He did recall that the game was coded by a chap called Peter Jobate – a name not very common on the C64 platform, with no other games released.
Where is Pete now? Can the story of this game be solved as well as us find something?
