Add power-ups

If you do not have a bug, you can still add a power-up to yourself. Press Select whenever Lan says “OK” and put in these codes after you run your customizer. There are special customization symbols after Z (represented as “1”, “2”, and “3”). Note: You must have mod tools to do this.

    HP+350: GJHURIE2
    HP+1000: CNJDU2EM (Glitch for HP+1000 causes the panels to turn to poison after you walk on them.)
    Shield: EIR3BM3I
    Reflect: SK13EO1M (Glitch for Reflect causes you to get 1 less B. chip in the chip selection.)
    Float Shoes: PEOTIR2G
    Shadow Shoes: GKHU1KHI

SP Navis

Get five stars, then highlight the “Continue” option at the main menu. Hold Left and press R(2), L, R, L, R, L(2). If you entered the code correctly, the stars will move together. Continue the game and find the SP Navis.

If you have a Wood Style, equip Undershirt and set Grass in the Navi Customizer, or use a Grass Stage chip as your default chip. You cannot go below zero. Also, use the Sanctuary chip to change all your panels to Holy (you take half damage), then use Dark Aura (any attack that does less then 300 damage is blocked). You cannott get hurt.

Test fire Buster

Go to the Mega Man option at the start menu. Press L button to see Mega Man fire his buster. This is useful if you need to see if the Bug effects your Buster.

Secret Area 1

After defeating Alpha, continue the game and go to the Undernet server (behind the hot tub in Yoka). Jack in to where you get the forbidden program. You will then be in Secret Area 1. Note: You must have 100 or more Bug Frags to enter.

Secret Undernet area

In Undernet Area 2, note the middle part that has no entrance. Use the following steps to get there. At Hades Isle, jack-in to one of the statues. This brings you to a portal. That portal brings you to that middle area. Talk to the person in the middle area. He trades chips for Bug Frag. He also has a Giga Chip for sale there. In Mega Man Battle Network Blue it is Foldrbak and in Mega Man Battle Network White it is NaviRecycle.

Extra damage

Lay down a RockCube and GutPunch it. It will slide straight across the field, doing a lot of damage to anyone in its path.

Easy money

After you get the commendation from SciLab, go to the hospital and jack in the vending machine besides the chip trader. Go to the southwest and get the chip, which is 9,000 Zenny. After that, go to the east from the chip to find a Gambler. The price will rise as you win, up to 256,000 Zenny. Win them for a lot of money. Also, after you complete the game and defeat Alpha, go to the SciLab. Go to the Job BBS board. Do the job that involves collecting the legendary tomes. Go to Hades Isle and talk to the Ghost Navi. He will tell you to go collect three Tomes. First, make sure you have 7,000 Zenny. Then, go to the Undersquare and talk to the person on the right. He will trade the tome for 7,000 Zenny. Next, go to Undernet 3 and search for a person that will give you a tome. The last tome is somewhere in Undernet 6. Once you get all three tomes, do not go back to the Ghost Navi. Instead, go to the staff lounge. On the left shelf there will be a statue. Talk to the statue to get 300,000 Zenny.

1000 Barrier

Use the 500Barr Program Advance (Barrier R, Barrier100 R, Barrier 200 R) and either HolyPanel or Sanctuary to form an unbreakable 1000 point barrier.

Block Wind Boxes

Using a Barr10 or Barr100 will stop Windboxes from blowing you back, as it is considered a 0 damage attack.


FolderBoy’s quiz answers are 3-2-1-3-1. In the Blue version of the game, the quiz answers are: 100 L, Zoo keeper, Yasu, Aquaguts.


At the beginning of the game when Yai tells you to meet her at her homepage, after the dinner, try to go outside. After Mega Man’s dialogue, talk to the mother. You can now go outside. Go to Yai’s home and you should be able to duel her. You will get the Glide chip.


To make the LifeSword, use Sword L, WideSword L, and LongSword L. Note: The LifeSword does 400 damage.


Sometimes instead of having to opening the start menu, you can press L.


When you buy HPMemory, sometimes a new higher priced one will replace it.


Buying a Modtools for 5,600 Zenny at the Beach will allow you to add Navi customizer items with Error Codes.

Paladin Sword P chip

Get the Paladin Sword P chip from the number trader (03284579). The hero sword does 180 damage and cuts three squares ahead.

Recover 120 *

Hack into the television in the hospital to get a Recover 120 *.

V4 Chips

Normally, you can only get up to V3 chips of Navis. However, you can also get the V4 chips from Navis. You must have the Team Style and defeat the V3 forms of Navis under twenty seconds with Busting Level S. This is the only way you can collect all 85 Mega-Chips.

Easier chips

To get chips easier, use the collect NC program. It will help you get chips from viruses, even with a busting level of 1. This can be useful when trying to get LifeAura and other rare chips you can only attain with high busting levels.

P.A. chips

Most chips with the same name have different codes (A, B, C, etc.). Just combine chips of the same name with different lettering but in order. For example, Spreader, code M, N, and O. You should get H-Burst. It does 100 damage to your opponent’s area.

Easy Bugfrag

When you are about to fight Bass/Alpha, go to either Dez and battle him. Just when your about to defeat him, wait until he is about to attack. Immediate before he attacks, delete him and you should get ten Bugfrags. Repeat this to earn a lot of Bugfrags. Also, put the Navi program Collect to also get a GutsMan G or GutsMan V2 G every time you defeat him.

Bass’ true form

To fight Bass’ true form you must first do four things: Complete the game; collect all 200 regular chips; defeat Seranade; and spend at least 300 Bugfrags at the Bugfrag Trader in Secret 3. Once you have done all of that, leave the Internet and jack in again. Go to the bugfrag trader. This is where a weak Bass will fuse with Gospel (a wolf-like being made of Bugfrags) and fight you.

Proto Man

After completing the game, there will be a star next to “Continue”. Continue the game, then go back to the beach. Go to Hades Isle and to the room where Chaud is waiting. Defeat him to win Proto Man’s chip (160 attack; attack all enemies). Also, after you complete the game, go to Hades Isle where you battled Dex. Chaud will be there. Defeat Protoman to get his chip. After you defeat Darkman, you can challenge him again, and once more after you defeat Japanman.

Cube Air-shot

Get a Rockcube on the field and use any type of Airshot. The Rockcube should slide across the screen. Note: Make sure that there are no holes in its path or it will fall in.

Rocket GutPunch

To fire a GutPunch chip, hold A and press Right, Up, Left, Down, Right, Left then release A. This should make Megaman punch and the send his fist flying forward, smashing the first thing in its path.


Choose the Fan Battle chip after using the SandStge battle chip. Press A to create a fan on your side of the field. It will blow the sand tiles at the enemy, damaging them while pushing the enemy backwards.

Message about king

After you get the viruses in the machine in Scilab when you feed them 100 bug frags (the maximum), talk to the keeper. He will give you a message about their king.

Defeating Alpha

Note: You need any Wood Style for this trick. Charge up your Mega Buster. Immediately after Alpha shoots his laser, use the Tornado on him. Then, immediately use a strong Battlechip (over 100 in power recommended). Repeat this while dodging his attacks to destroy Alpha. Also, you must have the ElecGuts style. Once he shoots that giant laser, use the machine gun tech. Also do that in the beginning of the battle, when the core shows up. Then, use a hard core attack. Also equip the Airshoe program. When he cracks the floor after he shoots his machine gun, stand in the cracked floor to avoid taking damage.

Defeating Bass

Have ElecGuts. At the start of the battle, use a Battlechip 100 or Over Attack Strength so the aura will disappear. Then, charge up your buster. When he does his attack when he gets his aura back, launch it. After that, use the Machine Gun Tech. Repeat this until Bass is defeated.

Defeating Beast Man

When fighting Beast Man, try to stay in your middle panel. It is easier to dodge his attacks that way.

Defeating Desert Man

Use any Aqua-type chips to darken Desert Man’s body and slow him down. When he turns into dark-brown color, you can hit him with your strongest chips. The Aqua-Shield style would be more convenient, since you can charge your Buster into a Bubbler and shoot it at anytime.

Defeating Kingman

When you netbattle Kingman.exe, get full power. Blast the pawns and delete Kingman.exe from Magaman.exe.

Defeating Proto/Alpha

Have the Reflect program. Get a Wood style (Wood Shadow is best, but use Weapons+1 with it) then put Hi Power chip and two to four Invis * and P.A.’s chip sets, such as Gutman Dashast and Guard. When in battle, use the charge attack when his core is covered, then blast him as hard as you can with Battle Chip. When his is using an attack and you cannot get close enough, use the Reflect maneuver to get his core open.

Defeating Serenade

Use a LifeAura to activate a barrier which can repel damage less than 200. Serenade’s attacks always strike 100 damage.

Fighting Roll

After beating Rank 8, Roll calls you. Go to Roll’s house and the game will state that the door is locked. Go to Higsby shop. Stand next to Higsby and you will see something you can go into. Go into it and press A. You will see Mai and she will ask if you want to battle. If you defeat Roll, you will get Flower Petal V2, which lets you copy one of you opponent’s move.

Fighting Tamako

After you get Metal Man’s V2 chip, Tamako will always want to Netbattle. Do not Netbattle her if you want Metal Man’s chip, because you will only get 100 Zenny.

Mario reference

Go into Yai’s house. Look in the main room. Hanging on the coat rack is Mario’s outfit.

Mega Man Legends reference

Go into Yai’s house. Look on floor to find a Lego-like character from Mega Man Legends .

Mega Man Zero reference

When you first walk in Dex’s house, there is a Mega Man Zero mat on the floor.

Zero reference

In Higsby’s shop, there is a poster of Zero calling him a hero.

V2 and V3 Navis

After you defeat a boss Navi, some dead-ends will reveal a V2 (version 2) remake of the Boss you defeated. They are harder and stronger. You will automatically get their chip. Then, in some areas of the cyberworld, you may randomly encounter a V3 (version 3) Navi. You will get their chip depending on how well you defeated them. The following is where you can find all the Navis:

    Flashman V2: ACDC 3 by the dead-end near the ACDC Square entrance
    Beastman V2: SciLab 1 in the bottom part where you first enter, turn right then straight up
    Bubbleman V2: Yoka 1 by Bug Dealer, on small dead-end walkway
    Desertman V2: Beach 1 to the right part of the Hospital Comp
    Plantman V2: Undernet 4 to the right part of the tower, near the warp point
    Drillman V2: Undernet 6 behind the Net Dealer
    Darkman V2: Secret Net 1 past the Monolith, turn right to the dead-end
    Japanman V2: Secret Net 2 past the Securtity Crystal on the top floor
    Flashman V3: Random encounters in ACDC 2
    Beastman V3: Random encounters in Lan’s Doughouse. Note: You need to use the Subchip “Sneakrun”
    Bubbleman V3: Random encounters in Beach 1
    Desertman V3: Random encounters in Yoka Inn TV
    Plantman V3: Random encounters in Hospital Comp 3
    Flamman V3: Random encounters in Yoka 1
    Drillman V3: Random encounters in Hades Net
    Darkman V3: Random encounters in Undernet 6
    Japanman V3: Random encounters in Yoka Inn armor case


Before the Bubble Man battle, you will get Guts Style which changes your character green and gives Mega Man new abilities such as a Tornado Charge Up. Sooner or later, you will receive a Shadow Style, a Team Style, and more:

    To get the Shadow Style, use Invisible or Invis. Battle chips.

    To get the Custom Style, use Battle chips.

    To get the Team/Brother Style, use Navi chips.

    To get the Shield Style, use Recovery and Defensive chips.

    To get the Guts Style, use your Mega Buster to delete enemies.

    To get the Ground Style, use chips that will change the battlefield. (for example, Grass Stage, Lava Stage)

    The Bug Style is very rare. This style can only be made by having at least one Bug and staying with it until you have unlocked this style. This style has bugs that either help Mega Man or affect him badly. The helpful effects (random) include getting your attack power increased to maximum, invincibility for brief time, and getting a 500Barr. One of the bad effects is that you sometimes lose health during the fight, or while selecting a chip. Note: This style is very difficult to increase. The two programs you will get when leveling up Bug Style are quiet useful. One program is StopBug, This program will allow you to program Mega Man any way desired without any bugs happening (errors are not involved in this). The other program is DarkLcns, which lets you connect with dark denizens (this program will always give you a bug, even if put correctly).

Fast Style change

Go to ACDC town and fight until you get a Style change.

Make Lighting, Salamander, Fountain, and Gaia Sword battlechips work

To make Lighting, Salamander, Fountain, and Gaia Sword battlechips work, you must have the corresponding element style:

    Elec style: Lighting battlechip
    Heat style: Salamander battlechip
    Aqua style: Fountain battlechip
    Wood style: Gaia Sword battlechip

Friendly viruses

Throughout the game, there are friendly viruses you can collect after you beat Flamman. They hide in a certain section and you will immediately get challenged by the entire family of viruses. When defeated, they get sent to the virus breeder in Sci Lab. The only way to get all the chips is by collecting all the viruses and talking to the scientist next to the virus breeder to get the virus’ chip. Their locations are as follows:

    Mettaur: ACDC 1 past the skull door.

    Bunny: Job 19.

    Spikey: Demon Comp directly north of where you enter.

    Swordy: Undernet 1 in the blue section’s second dead-end.

    Jelly: Beach 2 to the left of the Undernet entrance.

    Mushy: Sci Lab 2 to the left of the Sci Lab Square entrance, in the tiny square.

    Momogra: Zoo Comp 4 where you battled Beastman.

    Killereye: Principal’s PC 1 near the entrance to Principals PC 2.

    Scuttlest: Note: There are two parts to the Scuttlest family. The first is located in Secret Net 1, directly left of where you enter. The second is located in Secret Net 3, all the way north of the press pathway, to a dead-end.

Beast Man

In the Zoo, pick these programs in order to get to Beast Man:

    Mouse virus: Cat program
    Frog virus: Snake program
