Dolphin offers three different methods to play your games using real Wii remotes.
The most straightforward one is to pair the wii remote to your computer over bluetooth and use it in the same way you would any other bluetooth controller. However, connecting it this way prevents many features from working correctly and isn't recommended.
In order to make full usage of your Wii remote you'll want to use one of the other two options:
## Passthrough a Bluetooth adapter
When using this method, Dolphin will take direct control of a USB Bluetooth adapter and use it in the same way a real Wii would.
- hardware compatibility is limited to a few models.
There's no practical way of installing a udev rule from within a flatpak (at least not without going against flathub rules), so the user must do this manually.
This method isn't as accurate as passthrough, but it has much better hardware compatibility and doesn't require installing any udev rules.
It only requires ```bluez``` which is bundled with the flatpak, and ```allow=bluetooth``` which is enabled by default in the manifest. Coupled with the improved compatibility this means it should work outside the box for most users.
This env variable fixes a hypothetical case that could prevent Dolphin from running if it were set to wayland, it's unlikely but we keep it just in case.
Usually this would only happen if the user had globally set the variable in order to force qt applications to run on native wayland mode, otherwise it is safe to drop.
Only necessary when using "Real Wii remotes" in conjunction with the feature labeled "Emulate the Wii's Bluetooth adapter".
It's safe to disable if that feature is not in use, generic bluetooth gamepads will still work without it. Actual Wii remotes can also work without this option when using the separate passthrough feature.
