Getting the Nebula CD

First of all you need 10,000 Zenny and to be past the part where you fight ShadeMan in the ToyRoboComp and then you must find Django the solar Boy in Undernet 4 he will tell you about ShadeMan and how they fought and he needs the S. Sensor to destroy him.

Then you must go to Undernet 2 Area ( you'll have to go to the entrance of the area) (it's easier to logout and start form the NupopoComp in Netfrica) and find a purple HealNavi he will be complaining about how somebody stole his treasure and it was as shiny as the sun he will say the guy that stole it is in Undernet 6. Then you will have to go to Undernet 6 and look for a black HealNavi he will say that he'll give you the S. Sensor only for 10,000 Zenny buy it.

(be sure to have the 10,000 zenny I told you about ..


Navi Chips

Ok guys, there is a Navi in every major net area (like sharo, acdc 2, etc.) except for the metiorite. The navis and locations are as follows:

Aquaman: ACDC 1

Sparkman: ACDC 2

Gutsman: ACDC 3

Topman: Town 1

Roll: Town 2, underpart.

Fireman: Town 3, at edge of a circle

Numberman: Town 4

Woodman: Park 1

Burnman: Park 2

Videoman: Park 3

Netopia: Thunderman, edge of a circle

Sharo: Coldman

Netfrica: Kendoman

Yumland: Windman

I forgot who is found where in the undernet, but the people are searchman, protoman, shademan(random, in area w/dijango), laserman(in area w/bass statue), bass(most beat his statue), junkman, metalman, and I think thats it. If I forgot any navis, let ..


Beating Duo

To beat Duo, the chips in your folder should run smoothly, not having too many codes, and you chips should be above ground attacks,such as wide shot or life sword. Gun Sol chips are extremely effective against Duo, adn you should have 3 or four Invis* chips. Duo has four main attacks, one is the big fist that covers 4 squares. The others are the Duo Laser, meteor fist and the giant Arm that covers 6 squares. The laser is easy to dodge, all you have to do is go to on of the side rows and dodge the rings by moving foward, then back and foward again. The giant arm covers 2 rows so you would stand in the first row and then move back because he's going to hit again. The meteor fist has no specific place that you can dodge::best way is Invis.


Lots of hp

When your at castiloco *sorry for spelling im 9* go to the ice cream stand in the square jack in and keep walking around each time your hp life is small it gives you more hp. Often I always are at 1 hp at end of battle then i get a hundred after for rewerd

Bass SP/Ω

After defeating Bass, enter Black Earth 2 and beat the DS forms of the Navis whom MegaMan can perform Soul Unison with, then defeat MegaMan DS. Jack Out, then return to Black Earth 2 and wander around. Eventually, you'll encounter Bass SP as a random encounter enemy. Beat him with a S-Rank for the Giga Chip [DeltaRay].


Varsword codes

NeoVariableSword codes

1.Select a NeoVariableSword in the custom menu

2.Press "OK"

3.Hold "A" when that chip appears and quickly input one of the codes below:

Code Effect

Down, Right, Up Cross Sword

Up, B, Down, B, Up, B Double LifeSwords

Left, Right, Left, B Piercing Sonic Slash


Easy Getting Around

A good way to stay alive is to get the navi cutomizer program air shoes and use a chip like geddon 1 or geddon 2 that way you can walk when there are no panels though and even better tip is to get the flot shoes program which means you are uneffected by the panel type so fire does not burn you swamp panels don't drain you you don't slip on ice and cracked panels don't break. Though the only problem is that if an enemy uses geddon two you can't go across no panels.


Find the Cyber Bats

Usually when you are finding the cyber bats (when you are chasing Roll and ShadeMan) they run around in circles so you should go the opposite way and grab them.Catch those cyber bats.


SP Chip

It's easily to get SP chip?

how? the answer is using the PROGRAM ADVANCE

Like Hi-cannon a/b/c = GIGA CANNON dmg 500,

TIMEBOMB j/k/l = TIMEBOMB 600

and 1 important, airHok u/v/w = ProtHok 3 Dmg 200

Try It and Good Luck!!


Darkchip

to use dark chips you have had to beat shademan for the second time and in battle get hit 4 times without fighting back and your emotion screen should be green keep it like that until the custom screen and open it and then there will be 2 darkchips. dont use them megaman turns black after you use them and your max hp lowers by 1 and you cant use light chips or unite chips. if you use dark chips alot megaman will be used to the darkness and he wont need to get hit 4 times. warning remember no light or unite chips


Dungeon!

There is a large hole in the Ura Internet area 6 that is surrounded by purple slime on a platform and in order to reach the secret dungeon, you need to have these chips:

Bug Curse, Muramasa Blade, Black Wing, Element Dark and Poison Anubis.

Once you have those then when you get close to the hole, it will suck you down into the secret dungeon called Black Earth!!!
