''Zap't'Balls'' was released by [[EGS|Elmsoft]] (Elmar Krieger) in 1992, and is a conversion of the arcade game ''[[Pang]]'', which was only ever released by [[Ocean]] in cartridge format for the Plus machines. Elmsoft, who was an experienced demo coder, used a lot of effects and tricks from the CPC demoscene to polish up this game. According to an interview in the April 1994 issue of ''[[Amstrad Action]]'' (issue 103), he offered to convert ''Pang'' to the normal CPC machines, but Ocean refused. However, he had spent too much time working on his conversion to abandon the project.
The game itself is available in two versions: ''Zap't'Balls'', which was originally released as a 29-level 'demo' on the coverdisc of the German CPC magazine ''[[CPCAI|CPC Amstrad International]] '' and could be freely copied, and as ''Zap't'Balls: The Advanced Edition'', the complete version with many more levels, which was released commercially. ''The Advanced Edition'' also contained an intro that was originally planned as Elmsoft's part for the [[Cuddly Demo]]. Both versions require 128K of memory.
It has been said that Elmsoft promised a sequel, but only if nobody would crack his game. However, only a few weeks after the release of ''Zap't'Balls'', the French cracker [[Chany]] of [[NPS]] cracked it and distributed his crack widely.
