What is the problem? (only list ONE problem per report)

X-input pairs but no input works. Switch mode some buttons work but the analog triggers do not work and the digital trigger buttons do not work. I have attached a debug trace for each mode. the button order is:
a
b
x
y
start
select
home
l
r
l2
l3
r2
r3
d up
d right
d down
d left
p1
p2
left analog (up,right,down,left)
right analog (up,right,down,left)

This is my first time trying to use debug. If something is wrong let me know and I will try to fix it!

What did you expect to happen?

For one of the modes to work with blueretro.
