Habisoft published a series of ports from CPC that expanded the PCW library with more dk'sound: ''Abbey of Crime''; ''Hero Quest''; ''Knight Lore''; ''Pac Mania''; ''Spirits''.

The conversion trail was followed by Kachorro in its Spectrum ports of ''Barbarian'', ''Coliseum'', and ''Xecutor''.

Port $80 is used to send a value to select a register. Port $81 is for associated data; both support reading and writing. Similar to the operation of integrated circuits such as the PSG or a VDP, it allows sending many values with a minimal interface.

This is how '''KachorroSoft''' created the incredible colour ports of '''AMC''' and '''MadMixGame''' with graphics from the CPC; '''Phantis''' from MS-DOS CGA and CPC; and '''Hundra''' from the ZX Spectrum. But with new colour palettes.
