Just a stupid Question

[H4X0R]

Is the RazorX really necessary if i wanted to add a second nub to my psp, like can't i just solder some wire from the second nub to the Circle, C, Square, and Triangle pad?

If it were that easy dont you think the second nub would have been discovered alot sooner than now?
The board is an essential part of the process as far as my knowledge it converts the signals to the analogue ones.

Yes.

It is needed.
