myCade-hat batocera findings

up,dn,lt,rt - D-Pad directions
B1-6 Face buttons. usually assigned as North, South, East West, L Trigger, R Trigger
F1-3 Front panel buttons. usually Start, Select, [other]

in the MAP columns, the label is what batocera reports when configuring the controller.
MAP4 uses map=4 gpio=6,12,20,16,24,15,5,11,8,25,9,10,15

the * in the GPIO column indicates that I didn't check which exact face button corresponds 
with which pin, but that group are all together just possibly in a different order. 
physical button layout: 

B1|B2|B3
B4|B5|B6

for reference with the MAP columns, they all refer to the same button. 
i.e. real B1->MAP1 b6, MAP2 na, MAP4 na
