Homebrew vWii/Wii HID USB support - Why is it limited to Nintendont ?

[Cyan]

I wonder why the gamecube games (nintendont) can use HID/libwupc and Wii games doesn't.

because when you play a gamecube game, the Wii(U) is NOT running the gamecube game, it's running nintendont.
nintendont is the one in memory, responsible for interacting with the hardware and intercepting the game's function, sending them to the Wii corresponding CPU/GPU equivalent function.
Nintendont has HID support if you enable the "controller emulation" option.
if you enable the "Original control" (not sure about the name), then it means it's using the official nintendo's gamecube game controller function and physical port on the Wii (missing on WiiU of course) to read the controller's data. If you enable it, you lose all button combo and support for additional (non gamecube) controllers.

Either you tell nintendont to read the devices and emulate the controls by replacing the data into the RAM when the real controls are supposed to be read by the game, either you let the game read the data itself.

when you play a Wii game, there's no "USB Loader" in RAM, the console reboots and has only the game in RAM. if the game has no function to read HID, then you can't use HID. no "intermediate application" in RAM which can run at the same time than the game to rewrite the controller's RAM by reading external input devices.

PS3/PS4, as far as I know, is a HID controller

So it is possible to play the emulators in vwii mode with different bluetooth controllers? Help me out here

no...

you can at most play wth
wiimote+nunchuck
wiimote + classic controller
wiimote+classic controller pro

and at most is the emulator supports it some do like n64/ps1 and so more you can play with
wiiu pro controller
wiiu gamepad

That's not completely true. I was able to get a Blueretro device working with the Wiimote Ext port (the port on the bottom of the Wiimote) with a Retro Rosetta. You can read my post about it here, and I have everything from 8bitdo controllers to N64 NSO and PS4 controllers.

with the Wiimote Ext port

So your blueretro device (or the Retro Rosetta?) is emulating a classic controller and Pedro was 100% correct / the device is handled here:

wiimote + classic controller

Correct. I said it wasn't completely true.

Correct. I said it wasn't completely true.

it is absolutely true... lol

that is like saying n64 is only compatible with n64 controllers and you say oh not it isn't exactly true because you can buy an adapter that turns a gamecube controller into n64 controller input and play with that...(i own one)

it is exactly true what i said, if a device mimiks any of those devices perfectly it will work as well but the emulator only supports those input controllers.

there are adapters for every console in existence that doesnt make anyone saying that n64 is compatible with ps3,ps2,gamecube and so on controllers...

Look guys, I'm not willing to get into a war of words with you all, because honestly it does not hold my interest. I've posted information above, people can read it if they wish. I just want to help spread that info so it can help somebody else. So I'll just politely remove myself from the table.
