Now click and install the Handheldcompanion.exe You will need to restart your Ally after the installation.
Enabling Handheld Companion
Open up Handheld Companion.
Handheld Companion needs to be launched prior to any game launcher so you want to make sure that all game launchers are closed prior to starting the service. I personally don’t have any game launchers starting at launch with Windows.
Go to Settings and enable Auto-Start, Open application in background and Close minimizes. (This is a personal preference.)
Go to Hotkeys tab on the left. From here you can set up Hotkeys for different functions in the app. We want to create a hotkey for the quick tools window, I chose left on the d-pad + the button A. You can choose whatever you want.
Now you can press the hotkey at any time to bring up the Quick Tools window and make it disappear.
Handheld Companion is now Enabled and has a hotkey function.
Go to the Profiles section, Turn on Thermal Power (TDP) limit
Change the TDP to whatever you want. For my example I changed it to 7W.
Press the quick tools window hotkey you just created. A menu should pop up on the bottom right of your screen. You can press LB and RB to move through the tabs. Move over to the third tab and scroll down to Motion control settings.
Configure your Motion control settings like I have on my screen. Output device is Right Stick and Style of input should be Joystick Camera.
Motion activation can be set to Enabled (Turn off with a button) which means Gyro is always on unless you hold the hotkey. Disabled (Turn on with buttons) means you hold the hotkey while playing to use the gyro. I play with Disabled and I set mine to the Left Trigger. So when I hold the Left Trigger button while playing it will activate the motion settings.
You also adjust the deadzone and sensitivity as well.
Minimize Handheld Companion and launch any game.
Once the game launches and you’re in the game, press and hold the Gyro hotkey and swing your ROG Ally around.
Click the Profiles tab on the left side panel, scroll down and click Controller layout.
You can remap all the buttons on the ROG Ally and create & share custom layout templates.
