[Wii U] Erratic input management on most cores

[MeisterLLD]

Description

On most cores (everyone I've tried besides FB Alpha and Mame), input management is very erratic on Wii U.

• the only working controller is the Wii U Gamepad, and only if it is set as port 1 input
• even when "all users control menu" is on, it does not work most of the time. For instance if my Wii U Pro Controller is connected before opening retroarch, and even if I set it as port 2 input, it can't control the menu. If I connect it after opening Retroarch, it can, until I change inputs, then even if I come back to the Wii U Pro Controller, it can't control the menu anymore.
• The Gamecube Controller (Mayflash USB adapter) seems to consistently be able to control the menu though
• If I set something other than the Wii U Gamepad as port 1 input, then I can't control anything anymore, sometimes not even the menu (I mean : even the Wii U Gamepad can't control the menu anymore)
• Weirdly enough, hotkeys work fine in game. E.g. if I set the Wii U Pro controller as port 1 input and bind some hotkeys on it, game inputs are not recorded but hotkeys are.

Expected behavior

• Controllers set up as port 1 input should be able to control the game
• All controllers connected and setup as port x input for some x, should be able to control the menu, once "all users control menu" is setup.

Actual behavior

See description.

Steps to reproduce the bug

1. Open RetroArch, change port 1 input from Wii U Gamepad to something else

Bisect Results

Happened since as long as I can remember, even though I haven't been testing intermediate builds since around a year ago and until now.

Version/Commit

Latest nightlies.

• RetroArch: latest nightly.

Environment information

Wii U.

It might be interesting to note that FB Alpha and Mame work fine, and those setup initially Wii U Gamepad to "port #0". It also seems to me that there is something fishy about a +1 translation, since I have the impression that port #2 controls the menu in other cores. I've just found out that if I switch port 2 from, say, Wii U Pro Controller, which could control the menu just before that, then it can't anymore.

Good temporary fix : use core settings to remap Port 2 to Player 1 (and Port 3 to Player 2 etc). This works flawlessly. But the problem is that then one cannot use hotkeys anymore...

Hello. Did anyone find a solution to this ?
I would love so much to use RetroArch on my WiiU but I cannot play with my pro controllers only and this ruins everything... I would love so much to be able to set the Wii u gamepad to Port 5 and the pro controllers to ports 1 to 4 (with the home BTN working on pro controller).
Please, I'm waiting for this for years now and it would really be a dream come true 😘

Yes. What I've written just above your post works perfectly (and is the ONLY solution that works). Except for hotkeys... Home button works. Do this procedure core by core and use "save core remap" (or something like that) so that it remembers it next time.

Cool I have to try.
Should I remap ports for every cores one by one though ?
Edit : sorry, I did not understand your post completely. Thanks a lot.

Sorry to disturb, but I really can't find where to remap ports for each core
Could you please help me ?

Thanks so much man.
It totally worked. I'm so happy.
Thanks again ☺️
