Historically, only one commercial program, published by Ocean, ''"HeadOverHeels"'' by Ritman and Drummond, supported the AY chip on the PCW.
Habisoft published a series of ports from CPC that expanded the PCW library with more sound: ''Abbey of Crime''; ''Hero Quest''; ''Knight Lore''; ''Pac Mania''; ''Spirits''.
Later, it standardized the possibility of ports from the ZX Spectrum to PCW: ''Movie''; ''Fat Worm''; ''Nonamed''; and ''Phantomas2/Vampire'', which used the PCW's buzzer as the Spectrum's beeper. Some of these also incorporated AY music.
