Wow, I am surprised very few mentioned SEGA Master system pads or SEGA Genesis pads!
All Amiga Joypads are irrelevant once you use these. They have the 2 buttons that not a Single Amiga joystick has. That is Buttons A and B or rather B and C on a SEGA pad. Many Amiga games use this feature, Such as Turrican 1,2 and 3, Project X and a few other games I cant think of right now.
I can never use a Joystick again after using these.
I suspect the HoneyBee CD32 pad is even better.
but credit indeed must go to joysticks Like the WICO and Zipstick and Cheetah bug.
