Amiga CD32 joypad frustrations

This. There are a lot of rumours out there on swapping pin X and pin blah to get Mega Drive pads working on Ami's, but they're never completely functional. (Usually just the D-pad and A (or is it C?)).

Based on the schematic linked earlier, and the prototype I built on breadboard linked earlier also, I just built a new controller from scratch using an off-brand Mega Drive controller. So far it works flawlessly, even in Alien Breed 3D.

Finally confirmed that a resistor is indeed part of the design between LS125A pin 1 and pin 2 .

check the last sheet, the controller schematics, in specific R16.

They use a 4.7K resistor in there between VCC (or LS125 pin 2 [= PAD P7]) and LS125A pin1 (= PAD P5), exactly as I did (simply different value).
