Most native features *should* just work (with the exception of things like firmware update). If you find something that's broken please create an issue.

### How it works ### How it works
MissionControl works by Man-In-The-Middling the `bluetooth` system module and intercepting its initialisation IPC commands and system events, and translating their data to convince the Switch that it's communicating with a Pro Controller. MissionControl works by Man-In-The-Middling the `bluetooth` system module and intercepting its initialisation IPC commands and system events, and translating incoming/outgoing data to convince the Switch that it's communicating with a Pro Controller.
To achieve this, the `btdrv-mitm` module obtains the handles to `bluetooth` system events and shared memory when the system attempts to initialise them over IPC via the `btm` and `hid` modules. It then creates its own secondary versions of these and passes their handles on instead of the original. This allows modifications to be made to any data buffers before notifying (or not) the system. Additionally, the `WriteHidData` IPC command is intercepted to translate or drop outgoing requests to the controller. In the case of the latter, fake responses can be written directly to the buffer in shared memory.
