/*  Turns out a dance mat can be detected! The buttons are weird as heck though. 
 *  Here is a mapping
 *  
 *  Top left (x) is "Buttons6"
 *  Up is "Buttons2"
 *  Top right (o) is "Buttons7"
 *  Left is  "Buttons0"
 *  Middle is "Y"
 *  Right is "Buttons3"
 *  Down Left (Triangle) is "Buttons4"
 *  Down is "Buttons1"
 *  Down Right is "Buttons5"
 *  Select is "Buttons8"
 *  Start is "Buttons9"
 *  Middle Area is "Y"
 *  
 *  
 *  
 *  For each button, the state "128" means it is pressed
 *  The state "0" means it is not pressed
 *  However, the middle button has it's own state (I fugure this is actually recognised as a stick tbh)
 *  65535 is pressed and 32511 is not pressed
