Mayflash Adapter Vibration Not Working

[onemaycall]

Hi I'm currently using the mayflash adapter as well for gamecube controller. When I test the rumble on the configuration, it works, but it doesn't work in game. I tried using constant, ramp, and sine and they all don't work in game, but it works fine when testing. I'm playing SSBM. Can someone help me?? I'm using the latest dolphin 4.0-8258
