Tempest X (psx Windows emulator) - how to invert x axis with a mouse/spinner

[KenToad]

So you can play Tempest X with a mouse if you have a playstation mouse. It works in emulators when you select mouse controls, but the X-axis is flipped compared to my Groovy Game Gear spinner. Does anyone know of an easy way to flip the X axis of the spinner so that the movement in Tempest X will be correct? So far, I haven't found a way to do so.

Does anyone know of an easy way to flip the X axis of the spinner so that the movement in Tempest X will be correct?

I wouldn't say it's an easy solution, but I think you can do an easily reversable hardware mod involving a DPDT switch on an extender cable.

When you flip the switch, the data lines are swapped and the spinner moves the cursor in the opposite direction.   

Obligatory reminder from Randy to make absolutely certain you get the pinout right.

A word of caution using a cable like that:  Don't assume the Red and Black are power and ground on third party cable assemblies.  The signals must be matched properly to the spinner inputs/outputs, or damage to the spinner will result.

1. Start with the TT2 compatible female cable here and the male equivalent cable (or this connector) that mates with it.  It's a 5-pin Molex Picoblade according to this post.
  or
Get a 5-pin Molex Picoblade extender cable.

2. Connect the 5v and ground lines straight through.

3. Use euro-style terminals to splice in a DPDT switch to swap the data lines like I did for the buttons on KADESTICK.

Thanks so much! Unfortunately, I don't think it's worth modding the hardware for a single game, but it is a good idea if I get desperate. 

As an aside, has anyone ever gotten a PC spinner like the TurboTwist to work on any version or port of Tempest 2000? Jag emulation was still really lackluster in terms of features, at least last time I checked.
