You cant interface this G-940 sensor in MMjoy2 - at least "PnP", their 6 wires suggest a "3D" sensor, reading X and Y axes simultaneous.
Don' find datasheet for 3338CH or P25769.
Case G-940 really use a 3D sensor, are a magnet at end of grip pole, this complicate use another type of sensor.
I didn't find it for the Chip No#s either so tried e153302 sensor in google which brought up links to IR Sensors eg for TV Remotes etc.... but no datasheet
