Step 5: Making Room for the Teensy
We need to modify the back of the SNES controller case to make room for the Teensy. The picture shows the 2 spots that need removed. First clip the plastic, then use the needle pliers to peel the plastic away from the base. When you are finished, it should like the bottom-right picture. The free space we just created is where we are going to put the Teensy.
