Just wondering if anyone else is having this problem. I get this issue using pocketnes and mamece. I first noticed it playing galaga. When holding down right or left and any of the four buttons above the thumbpad the ship will not move or fire smoothly. I tried assigning the fire button to the top two buttons by the ear piece and it works fine. Just wonding if there might be a multiple button press problem with the thumbpad and the four buttons right above it.
