I had an sx1 giving some problems closer... i discover it playing super stardust cd32 version using the sx1 rgb output for better picture quality, with sx1 connected extra buttons of the cd32 pad were ignored.
I have the same problem when I plug the "Analogic's CD32 disk drive" (

Any hints or solutions to this??
