yes it is possible, lets just wait for the devs to add it.

U mean they‘ve already done the work of vibration fucntion？

Haptic feedback has been discussed already and concluded that it would kill battery in minutes, it's not practical, so most possibly not going to happen.
If you don't believe me, force with an app or something your Android phone to constantly virbrate and count how long it will last. You can multiply the time with something like 2.5 then devide it back to half (because of CPU stress power drain) and you get the most time you will spend playing a game until it goes to 0%.

So，u have already done the test with haptic feedback which may led to a great lost of battery running the emulator，or is it just ur hypothesis about losing battery that much. I think it's really important for portable device to have haptic feedback since it has no such physical buttons, even it may bring battery issue.  Besides, many people in Chinese forum even said that they would like to play certain games immediately once haptic feedback was added. I think it is really sweet of Drastic NDS developers having added an option of haptic feedback. About battery issue, i think it is wisdom to let users to weight themselves. And i really appreciate that u guys could take this into consideration. Thanks!!!
