Anyway of showing how much battery life is left on controller. If you dont pay attention to controller, it goes out in the middle of a game. This way we can pause game and change batteries. Similar type of option like snes9x-gx.

What version of the emulator are you using (official, SVN revision,...)? latest..........679

Please provide any additional information below (Emulator settings, Console setting,...)

Wii 4.3U..........Homebrew 1.1
