Nintendont 8bitdo adapter

Hey everyone, I'm having loads of trouble with my wii u right now. I recently modded it so I could load up dumps from gc and wii disks. I tried to figure out how to play a gamecube game (I was testing with mario power tennis) with my ps5 controller. Wiring it doesn't work, I think I need a Y cable for that for more power since the ps5 controller pulses orange then turns off. I turned to my 8bitdo 2 adapter since it's supposed to work. I connected my ps5 controller to it, it didn't work. I tried putting it into ps3 mode, still didn't work. In the ini files provided with nintendont I see that a ps3 controller should work, but it wasn't. I'm using aroma and I'm using UWUVCI AIO to be able to install my gc games as virtual console games. For mario power tennis there isn't a community ini, but my settings are the default. Do I need to disable gamepad input when I make the wup file on UWUVCI? Is there a setting I need to mess with in nintendont? Any direction at all would be super helpful, thanks!
