In 1986 the rather popular machine Ghosts N Goblins appeared in the amusement arcades. In this game you controlled the knight Sir Arthur through seven sideways scrolling levels, which needed to be crossed by jumping and throwing weapons.
In the same year the game was converted for the C64 by the company Elite, whereby Chris Butler was responsible for the conversion. From the seven levels of the original only four are left on the C64 version, which is connected to the fact, that Elite - which had given the job for the conversion to Chris Butler - insisted on the precondition, that the game should be completely in the memory without having to reload from a media.
