Razer Tartarus V2 Pro - can the Analog Thumbstick be set to "Left Stick", instead of "Right Stick"?

As far as I know, Razer is preparing firmware to allow this (switching between left or right joystick) - so stay tuned.

I have found a solution with Joytokey you might try.

See my post here : 

It’s ABSOLUTELY MENTAL, that Razer released this product without this feature. Of course the thumbstick should map to the left controller stick for movement.

I have a £150 Razer mouse for the aiming, why would I want that on my left hand too!!!! Like seriously, this should be the default!

Also, there doesn’t seem to be a mapping option for clicking the thumbstick when in analog mode. Something else I’m going to have to fix. Pretty crazy considering the cost of this thing!

Did anyone even use the product before they starting selling it?

Anyway, I got it working for Geforce Now. You can fix this by adding the following as a user variable in your Environment variables (for you non-techies, don’t include the double quotes, just the text in between them):

Variable name: “SDL_GAMECONTROLLERCONFIG”

Value: “ [removed by moderator] 000eb [removed by moderator] 0,Razer Tartarus V2 Pro (sticks swapped),a:b0,b:b1,x:b2,y:b3,back:b6,guide:b10,start:b7,leftstick:b9,rightstick:b8,leftshoulder:b4,rightshoulder:b5,dpup:h0.1,dpdown:h0.4,dpleft:h0.8,dpright:h0.2,leftx:a2,lefty:a3,rightx:a0,righty:a1,lefttrigger:a4,righttrigger:a5,platform:Windows,
[removed by moderator] 000eb [removed by moderator] 0,Razer Tartarus V2 Pro (sticks swapped),a:b0,b:b1,x:b2,y:b3,back:b6,guide:b10,start:b7,leftstick:b9,rightstick:b8,leftshoulder:b4,rightshoulder:b5,dpup:h0.1,dpdown:h0.4,dpleft:h0.8,dpright:h0.2,leftx:a2,lefty:a3,rightx:a0,righty:a1,lefttrigger:a4,righttrigger:a5,platform:Windows,”

Once added, restart Geforce Now if already running. Geforce Now reads this mapping on each startup. The above just switches the thumbsticks.

Working on a Steam fix also. Coming soon...

Considering my last comment was moderated, I have a new method that shouldn’t offend the moderators and that works with Geforce Now and Steam.

Run the following Powershell script. It will ask you how you want to map the stick. Select option 1 (select option 2 if you want torevert back to the default) for movement.

This works for Geforce Now and Steam. If either were open when you ran this, make sure to close them and re-start them as the setting is pulled in at startup.

For Steam you also need to ensure your game’s controller settings are set to “Enable Steam Input”: Right-click [GAME] → Properties → Controller and set it to "Enable Steam Input".

Happy fraggin’ fellow Razer lovers :-)

}

how run this powershell script to get it to work for left stick movement?

1. Open Powershell prompt. I ran it with Powershell 7, haven’t tested with other versions.
2. Copy the entire code into the prompt as it is.
3. Hit return to execute
4. Follow the options.
