A user over at http://www.atari-forum.com
is producing some adapters for Playstation pads to enable them to be used on the Amiga, Atari, Spectrum etc.
I am trying to get the developer to add CD32 support out of the box either in addition to current functions or as a special edition.
The prices are not bad, £15 in kit form, £20 assembled as an extension cable or £23 assembled including PS2 Analog pad.
Well I'm getting one.
