Teensy Help

[DE4THRE4P3R]

Ok, so i uploaded the code to the teensy and it just keeps spamming "A" like as an input. Any suggestions? My soldering may not be the problem since its reading the input.

EDIT: forgot to say this script also helps so you can use more buttons at the same time so like you can hold A.B.X.Y and any D direction at the same time,

Hi D56,

I need your help please.
Could you write a teensy LC's code for more triggers.
I would like a gameboy zero with L1 R1 and L2 R2.

thanks a lot.

Can't test it myself, but it should work.
Pin 13 and 14 are the new lower shoulder buttons.

It wasn't the code. it was my soldiering. Some of the D pad controls were bridging the ground point so when i get a day off im gonna go back and fix it. Thanks Guys!!
