Well you can goto
www.maxking.com and buy a chip programmer and while your searching there you can also dl the neo 2.2 code.
Another place to ck to build your own when u gather all parts is
www.jdm.homepage.dk/pcb2.htm I am presently puttin one together from here just waiting on 2 transistors on back order.
I had a buddy program a chip with neo2.2 code from maxking and it works better than one i had bought off gamegizmo. GOOD LUCK
