A surprising number of FPS titles support the CD32 pad - even ones that weren't released for CD32.
I am a bit confused by the image, though. Usually buttons are on the right while the stick is on the left and buttons are placed slightly higher than the stick. In this case it looks like the buttons are either placed below and in reverse of what is typical, or the stick is to the right of the buttons. Which is it?
As a lefty, arcade style layouts have been the only thing that ever worked for me, so I hope it's just untraditional button placement :-)
Also, would love a stick with more buttons and USB for the Sam (and various other newish things).
Ever since I ordered this
