Incompatibilities with USB ports for Hori Flex

[SinisterSticks]

Hello.  To paraphrase Sir mix A lot I like big sticks and I cannot lie,

Those thumb pads are a little too hard to wrangle and a little too hard to get exact.

For digital controls on video games I got a fight stick that has TRS interfaces that work with both the Xbox adaptive controller and the Hori Flex

The problem comes when it comes to analog games.

On the Xbox adaptive controller to controllers I want to use seem to work well with the Xbox adaptive controller.

The first one is a PC 15 Mission stick from interact and that plugs into a Rockwell pc15 to USB converter. 

The other controller I have is an icode Atari 9-pin to USB converter.  That way I hook up real 2600 paddles to play Warlords and other similar games


What you're supposed to do is plug a USB controller and the left stick ports and the right stick ports of the Xbox adaptive controller and Hori Flex

The problem is neither of them work with the Hori Flex.

It seems like according to hori's documentation on it you need to find d input controls.

I assume because the two controllers I mentioned work with Xbox therefore they're called X input controllers.

I'm trying to find a way to convert X input controllers it's a d input controllers.

Because if I can't with the icode brand Atari controller, I cannot get the real 2600 panels working with Warlords for Nintendo switch.

I guess there is such a thing as a pc-15 to d inputs connector.  I assume the ones that have no big box are exactly that.

If that's the case then that's the easy solution for the analog flight stick.

Now comes the problem with the Atari paddles.  I don't know of any X inputs to d inputs converters.  But one of those Brook adapters work as an X input to d inputs converter?
