Core/DolphinQt: Implement Emulated Balance Board.

[jordan-woyak]

Big thank you to @Pokechu22 for doing almost all of the work in #8268

I've done cleanups and final touches.

Any thoughts on these questions?

• Exposing 5 Wii remote slots when only 4 can be connected is kinda weird, but I guess that's an existing issue?
• Does "Step Off" under "Options" look fine? (it removes all weight when pressed)
• Is 60kg default weight fine?
• What range of weights do TASers want in the UI? (it's 0-136kg currently)

Actions like jumping or whatever can be added in another PR.

On real hardware, the balance board takes a wii remote slot right? So only 3 wii remotes can be connected while a balance board is connected? I don't have a balance board so I can't test this.

Yeah.

If I remember correctly, the Wii Balance Board uses slot 4? So maybe we can just gray out slot 4 when a Balance Board is selected and put a text bubble if you hover over it that the balance board uses slot 4? Otherwise, this looks good to me.

[Pokechu22]

IIRC there are some technical reasons for using slot 5 that I don't remember the details of (something along the lines of hardware supporting more things connected, but software rejecting it). I do remember that Marble Saga: Kororinpa supports both 4 Wii remotes and the balance board (though not at the same time; IIRC it kicks out the 4th Wii remote when you switch to balance board mode, and doesn't let you connect a balance board when not in balance board mode).

[JMC47]

I mean, I'm not going to split hairs over it. So if we want to do a balance board as a separate slot and still allow people to configure all four wii remotes, I'm fine with that.

[jordan-woyak]

Yeah, the "Real Balance Board" already had the fake 5th-slot existence before this change, it's just a bit more obvious now.

[jordan-woyak]

I'd appreciate if someone can test TAS recording/playback stuff. I only have a vague idea of how it's intended to work.

[JMC47]

I recorded a short TAS of Wii Fit completing a body fit test, and everything worked as I expected. I was able to shift around my weight using the TAS input, there were no crashes, and everything played back correctly.

I also did a small TAS test this morning experimenting with a couple of the balance games, and I can report that things worked correctly as well.

To answer these questions from a TASer's perspective:

• Is 60kg default weight fine?
• What range of weights do TASers want in the UI? (it's 0-136kg currently)
  I think that what's there is perfectly reasonable.

[jordan-woyak]

Thanks for testing. I just noticed the Profiles box is showing normal Wii Remote profiles. I'll get that fixed. That's fixed now.

I'm going to try to improve the "Step On/Off" user experience.

FifoCI detected that this change impacts graphical rendering. Here are the behavior differences detected by the system:

• sfa-shadows on ogl-lin-mesa: failed to render

I tested it, Balance Board emulation works!! Amazing job jordan-woyak!

It is possible to map Mouse movement if the cursor directions are mapped btw. Amazing work nontheless.

Confirmed working without any issues
