This is for the level when you are on the boat and something happens in the engine room and you got to crack the hard password but I'll tell you the password. Double one & nine too tonight makes eleven, and the password for the puzzle is 11922911.
If you insert any Megaman Battlenetwork game(except for battlenetwork 6) there is hidden items unlocked. Most noticable is if you put in any of the games execpt for the battlenetwork 5 games, during virus battles, the music changes from the usual to a theme off that game that is insterted. Also you can get cheap Subchips from inserting battlenetwork 2, and get some programs at a navi in one of the end areas, and the cheap subchips are at Lan's fathers room in Scilab which are half price. That is the ones I've found so far besides the advance list on the boards from inserting battlenetwork 4: red sun/blue moon.
Darkchips!!!!!!!!!!!!!!!!!!!!!!Added 12 Dec 2007, ID #5718
Darkchips can make you're megaman turn bad but here is a tip. If you use about 500 darkchips you're megaman will stay dark forever and you can use strong megas like anubis, miromasa, blackwing,etc. A giga would be bugcurse. You can only use 12 darkchips and you can start using those chips but you will start getting light very soon. Warning! Once you get dark you cannot use sp megachips but you can use ds megachips!Enjoy.
