The well received Commodore 64 version was developed at Elite in a very tight schedule (2 months), by:
Developer: Chris Butler
Graphics: Rory Green and Chris Harvey
Sound: Rob Hubbard
The Commodore 64 version's theme, a "funky" version of the arcade, was created in less than 12 hours by Rob Hubbard, " started working on it late at night, and worked on it through the night. I took one listen to the original arcade version and started working on the C64 version. [...] By the time everyone arrived at 8.00 in the morning, I had loaded the main tune on every C64 in the building! I got my cheque and was on a train home by 10.00". The music since then has reached a cultic status among Commodore 64 enthusiasts - nearly everyone who ever had a C64 knows and recognizes the tune. The song is available from the HVSC. The cracking group Lurid Tricycle considered the Commodore version so easy that they added an un-trainer, to make the game harder. ( Anm. Olli: Nat. Quatsch, gilt nur für Durchgang 1, und auch für den brauchte man ne Menge Übung ) .
