Title: Tempest X (psx Windows emulator) - how to invert x axis with a mouse/spinner
Post by: KenToad on October 03, 2020, 03:17:21 pm

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.

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.   ;D

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 (http://forum.arcadecontrols.com/index.php/topic,163588.msg1723480.html#msg1723480) and the male equivalent cable (or this connector (https://www.tinyosshop.com/index.php?route=product/product&product_id=308)) that mates with it.  It's a 5-pin Molex Picoblade according to this post (http://forum.arcadecontrols.com/index.php/topic,138305.msg1429504.html#msg1429504).
  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 (http://forum.arcadecontrols.com/index.php/topic,134781.msg1391665.html#msg1391665).

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.  :cheers:

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.
