[Bounty] Support rumble / force feedback on Dinput controllers [$50]

Hoping to finally get support working with Dinput controllers as I primarily use Wii U Pro controllers through the mayflash adapter and in Dinput mode, (actually xinput mode too for some reason) the controllers can not use rumble and I read this is a feature Retroarch lacks for dinput controllers

Well this doesn’t seem to be drumming up too much attention so in the mean time I’ve been doing some research I’m going to look into trying this method I found mentioned here following this guide here

I’d really love to get official support for this though so if there is anybody out there with the know-how to make this happen that maybe doesn’t think $50 is enough for the job please let me know I’d absolutely be willing to contribute more to the bounty if I knew someone was making progress on it
