Hmmm... doesn't that look quite much like Konix's Speedking, which has two button (Sega) versions too. Here's my two button Speedking and it's working perfectly with WHDLoad games etc with two separate buttons. In recent years I've learned that it's the best joystick ever 
Too bad I didn't have it in "golden years"...
That's a pretty neat looking stick. Wouldn't mind getting hold of one of those. Might make Mortal Kombat a little more fun. Though, I have gotten used to using the CD32 game pad.
