Add rumble support for the authentication controller on PS4

It should be possible for Xbox 360 / Xbox One.
Not sure if the Hori Pad FPS Plus emulation has rumble.

Not sure if the Hori Pad FPS Plus emulation has rumble.

Spoiler: It doesn't. PS4 does not even bother to send the report to it the last time I checked. Seems that some tweaks to the GET_REPORT 0x03 could change how the PS4 identifies the controller but I haven't yet figured out what bit/byte sequence enables the rumble support. (One easier but costly way is to just get a wired third-party controller that has rumble support, for example, Nacon Revolution Pro, and see how it differs from a, for example, Hori FPS) It does now, see below.

Thanks for reporting.

I managed to find the pattern: change the fifth byte of the GET_REPORT 0x03 from 0x41 to 0xff enables touchpad, LED and rumble. Not sure which one is which, though. Bit 2 seems to be required for the report to show up (and looks like it also enables LED, but it might be actually caused by the bits that I didn't turn off like bit 0). Also bit 6 is the touchpad as you may already noticed.

EDIT: Okay so bit 3 is for rumble. So if touchpad, LED and rumble are all you want you could set the fifth byte to 0x4d instead. I'm still not sure what other bits do so it is probably safer to leave them as-is for GIMX. (But feel free to research more if you are interested 😃)

Thanks for the tip!
