 `isActive()` | **bool** | Returns whether the library is active or not.

-`deactivate()` | - | Deactivates the library.
+`deactivate()` | **bool** | Puts the adapter into a low consumption mode and then deactivates the library. It returns a boolean indicating whether the transition to low consumption mode was successful.
 `serve([gameName], [userName], [gameId])` | **bool** | Starts broadcasting a server and changes the state to `SERVING`. You can, optionally, provide a `gameName` (max `14` characters), a `userName` (max `8` characters), and a `gameId` *(0 ~ 0x7FFF)* that games will be able to read.
 `getServers(servers, [onWait])` | **bool** | Fills the `servers` array with all the currently broadcasting servers. This action takes 1 second to complete, but you can optionally provide an `onWait()` function which will be invoked each time VBlank starts.
 `getServersAsyncStart()` | **bool** | Starts looking for broadcasting servers and changes the state to `SEARCHING`. After this, call `getServersAsyncEnd(...)` 1 second later.
