In Megaman battlenetwork 3 blue where can you get the chip Nobeam 2

Well, from an N.O-2 of course! Problem is they're hard to find. However, searching Secret 2 is the best way to go. Use the Collect program to ensure that you get their chip. Otherwise, abuse chip and BugFrag traders. Or trade it from another cartridge. Or cheat. One of the above.
