It would also be nice to remap Select and Start for non-emulator specific functions.
I know we need to have access to the keyboard and the emulator settings, but it seems that we could utilize the Power/Lock slider for accessing the emulator settings, like some of the other emulators currently available, and perhaps a combo-press of Select and Start to access the keyboard.
That way we could use Start (would be nice for Pause), and Select for whatever is needed.
Also, game specific settings would definitely be nice, but even if we could just have any button customization that'd be a good feature. We can always save our configs and re-upload them to the GCW when we need to.
