mGBA core enabling accelerometer/gyroscope option

So, I noticed this option in the options menu. Tried mGBA with games that uses tilt controls like Kirby Tilt and Tumble and Yoshi’s Universal Gravitation, and it looks like mGBA detects the device gyro, but the games don’t work properly yet, specially if you are in portrait mode, motion controls are all over the place.

So, I was wondering if this isn’t fully implemented, or if it’s a glitch or something that should be fixed/completed in future? Would be cool to use the device sensors for emus that support it.

Thanks!
