Is it possible to get rumble support added to the framework, so controllers with rumble support will vibrate when using games that support it?
The work to have it supported for the GBA is already in the core, but is not hooked up with the framework:

It could also be added into the Gameboy Colour core, and possible some arcade games.
The big one will be PS1 when it arrives, so be great to have this in before it one day launches.
