Could you add controller vibration/rumble support for mfi controller such like gamesir g8 plus mfi controller?

Is your feature request related to a problem? Please describe.
Yes. When using MFi controllers such as the GameSir G8 Plus in MFi mode with VoidLink/Moonlight on iOS, controller input works, but vibration/rumble does not. This leads to a less immersive experience compared to using controllers like the DualSense, where vibration support is available. For users playing games that rely on haptic feedback for combat, driving, or other gameplay cues, the missing rumble support makes the experience feel incomplete.

Describe the solution you’d like
I would like VoidLink to support controller vibration/rumble for MFi controllers on iOS, including devices such as the GameSir G8 Plus in MFi mode, if technically possible through Apple’s GameController framework or another supported method. Ideally, rumble commands from the host PC should be forwarded properly to compatible MFi controllers, just like other supported controllers.

Describe alternatives you’ve considered
I have considered using a DualSense or other non-MFi controller instead, since those may already support vibration properly. However, I specifically want to use an MFi controller like the GameSir G8 Plus because of its mobile form factor and convenience. I have also tested using the controller in iOS generally, where input works fine, so the issue seems to be specific to rumble support in streaming rather than basic controller compatibility.

actually I use a game sir g8+ for development, and the rumble works in DS4 mode (also recommend to set emulated controller to DS4 from VoidLink settings menu)
you may find a proper tool on PC to test rumbling before trying it in actual game, for example:

(I used another website in Chinese, so didn't try this one)

Hi,

I've tested rumbles with GameSir G8 Plus in MFi mode on an iPhone 15 pro. It works but it's hard to tell if the rumbles come from the controller or the phone itself.

In the meanwhile, I've also tested by replacing the iPhone 15 pro with an iPad mini 7 (which doesn't have built-in rumbles) into the same controller, same settings, and it doesn't rumble.

So that I supposed the rumbles do not come from the controller but the phone itself because why wouldn't it works on the iPad while it's working on iPhone with both the same settings ?
