tg16 / duo confusion..

Ok I need some help from you TG guys.. Specifically controllers.

First I'm to believe there are the following systems.

Turbo GraFX 16
NEC Super GraFX
PC Engine
PC Engine Duo

Not sure what is what...

and there are two type of controllers.

These are the pin outs..
(small connector) and
(large connector)



I found a few different controllers but all are the large connector types.

a



Could some one tell me the different types of controllers. I need to know what controllers match the large and what matches the small pinouts.

looks like the smaller is just non USA version of the bigger. They are pinned the same and adapters exist. So never mind, answered.
