When changing the Rotation option, the touch controls are not reflected

[anyputer]

First and foremost consider this:

• Only RetroArch bugs should be filed here. Not core bugs or game bugs
• This is not a forum or a help section, this is strictly developer oriented

Description

I am not sure if this is a RetroArch or Libretro core bug but, when you change the Rotation option in video settings, the touch and mouse controls are not reflected in the DeSmuME core, for example. At least the mouse controls make more sense as you know where you are clicking.

Expected behavior

Where ever you click / tap on the rotated image, it should work as expected.

Actual behavior

It seems that the touch doesn't rotate according to the setting.

Steps to reproduce the bug

1. Change the Rotation in the video settings
2. Load DeSmuME ( for example )
3. Make sure the pointer type is set to touch.

Bisect Results

Not even sure.

I'm linking this bug to the relevant libretro-desmume bug. the problem with such a broad project is that these sorts of issues require co-ordination.

Not sure about for touch, because I don't have a touchscreen, but I've tried setting mine to both touch and mouse and using emulated pointer on the right analog stick. There is an option that you can set in the quick-menu when a game is running where you can set the input_rotation. If I set this to 90, the pointer works as expected in a vertical game.

This would be nice to have. Palm OS Mu looks better on the Switch in portrait but the touch isn't rotated to match.

@azuravian fix worked for me

FYI for people using Palm OS Mu on Android I couldn't find any input_rotation option, but if you rotate RetroArch with the device's normal rotation features rather than the rotation option in RetroArch the touch input does get rotated correctly
