I set my default keys where Select was the letter N in the PC's Mortal Kombat Trilogy. When I went to select one of the four classics, I pushed N, and at the bottom of the screen an odd thing appeared that looked like this: P=23,X=42
The numbers would either go up, or down in sequence over, and over again. When you press N again, it disappears. I reset my Select button to another letter, and it only works when you push the letter N. Does anyone know what it is?
