this has been discussed many times b4 and it is only possible if u rewrite devhook's pspbtncf.txt and pspbtncf_game and the other text files because 3.02 oe emulates both kd(3.02) and kn(1.50) folder.
Might need to make a new devhook too I guess if theres a source for devhook some pro coder might be able to do it.
