Hint: Higsby's warehouse code:
The code at the second gate to Higsby's warehouse in Mega Man Battle Network 4 Blue Moon is "111" The other two are math problems and are easily solved.

Hint: Fighting Bass:
To fight with Bass, you must collect all six Soul Unisons. Then, go to Undernet 4 to unlock the door to Undernet 5. In Undernet 5, there are two megachips in Purple Mystery data; bring some Unlockers. You will then see a door in the farthest-most corner of Undernet 5. Behind it is Bass. In order to fight Bass, you also need the S-ID by collecting all 150 standard chips. There is a small path that leads to a path below Bass. Laser Man V2 awaits there for you to fight as well.

Hint: Defeating Burn Man:
Get chips such as Rockcube so you can block his Burn Attack and perhaps his Burn Slider.
Information in this section was contributed by lizard wizard.

To easily defeat Burn Man in the Hawk/Eagle Tournament, you need a lot of Aqua Chips like Bubbler and Wide Shot, or in Blue Moon you can use Aqua Soul. When going against Burn Man, enable Aqua Soul and charge up your Aqua Chips. Only use Wide Shot when Burn Man is in front of the burners. It is also easier if you use a Dark Chip, but it will deplete your maximum health.
Information in this section was contributed by Hyper Quickman.

Hint: Defeating Duo:
Make sure that your folder is equipped with chips that go above ground, like Wide Shot, Twin Fang, or something similar. Note: Flame Line will not work. Dodge his attacks, then when his middle is red you can do damage. Chips that work well are Gundelsol Ex (Number Man machine code 74293099) and Gun Sol (obtained at the haunted castle at Castillo; almost at the end there is a figure of the person who defeated Dracula, check his leg and get that chip). Use those chips and dodge Duo's attacks to complete that mode of the game.
Information in this section was contributed by JulianDaShorty.

An easy way to defeat Duo is to use PAs. Use a few like Lifesword and just dodge his attacks.
Information in this section was contributed by Jacques Albert.

When Duo does his laser, it has rings around it and they can hit you, even if you are not in the middle. Those rings have a pattern. To dodge those rings, do this when the laser starts. Go to the bottom or the top and move to the last panel, then go to the middle one, both in the top row.
Information in this section was contributed by lizard wizard.

Hint: Defeating Laser Man:
Note: This is an easy, but long way to defeat Laser Man in Mega Man Battle Network 4 Red Sun. First, use a chip such as Air Shot as a sacrifice to get Wind Soul, then keep firing your buster (which is an Air Shot), which does 5 damage each. This will also temporarily will stun him long enough for you to fire repeatedly. This will require about five minutes, depending on which mode you are in.
Information in this section was contributed by jacque goldsmith.

Defeating Shade Man:
The Gunsol chips are effective. If you use a physical chip he will go into his bat form. Attack one of the bats. Unfortunately which specific one changes each time. Try using a chip that stop time such as Magnums and Circgun. Navi chips such as Protoman and Sparkman will work very well with his bat form because they will find him. Also try using the Poisphar PA.
Information in this section was contributed by Nicholas Muriel.

Hint: Secret Battlechips:
Link with Mega Man Battle Network 4 Blue Moon or Mega Man Battle Network 4 Red Sun player and go to the "Comm" option.Then, go to "Waiting Room". Either the Red Sun player or Blue Moon player must select "Visit", then send the Navis to each other. Go to Higsbys Free Tournament BBS. When defeating the last Navi, you will get there Battlechip, for example a PropBom2 from Air Man and NumrBl2 from Number Man.

Hint: Evil chips:
Use the following trick to get the five evil chips easier. After you defeat Bass in Undernet 5, jack out then go back to Undernet 5 again. You will find black Navis. Talk to them. You must then fight ten battles. If you win, you will get an evil chip.
Information in this section was contributed by Chrismasterx3193.

Hint: V4 chips:
Go to the Bugfrag Trader Machine in Secret Net 3. Give lots of Bug Frags and eventually you will get a V4 chip for almost every Navi. Note: Before you get a V4 for any Navi, it is going to give you the other versions first.
Information in this section was contributed by Chrismasterx3193.

Hint: Unlimited Z Saber Battle chips:
This trick requires two Game Boy Advances, Mega Man Battle Network 4 Red Sun or Blue Moon and Mega Man Zero 3. Complete the boss levels until you are allowed to use the computer. Link with Mega Man Battle Network Red Sun or Blue Moon go to "Transmission" on Mega Man Zero 3. Trade chips with Mega Man Battle Network 4. It does not matter what chip you trade; some chips will give you new chip parts for Zero. After trading, the Z Saber will appear on the Mega Man Battle Network 4 screen. Note: You do not have to pick something else to trade. Z Saber does three hits for 100 damage each.
Information in this section was contributed by Luanarc.

Hint: Defeating Laser Man:
Go in the middle row. Go to the last panel and when Laser Man attacks, go up one panel. When at the middle panel of the middle row go to that panel. It will break because it was already cracked from the laser. Then, move to the panel behind the cracked one. When he uses the laser, it will not hit you because it will fall into the hole

You must be playing the part where the Net is divided. Go to Sharo. Go to the Space Center, and jack into the computer on your left. Once you get out of the homepage, talk to the Green Navi.

Information in this section was contributed by Ivanbass.

Information in this section was contributed by J-Man.

Information in this section was contributed by lizard wizard.

Do the Tayyoh! mission. Note: You must be outside somewhere. Netfrica is the best choice. Go to Undernet4 and talk to Django. Then, go to the entrance of Undernet2 and talk to the Heel Navi. Next, go to Undernet6 and pay 10,000 Zenny to get the S.Sensor. Go back to Django and give it to him. Watch the intermission sequence. If you want the NebulapCd, look in the coffin of Shademan.
Information in this section was contributed by Huy Nguyen.

Information in this section was contributed by Oybay100.

Hint: Life Aura: Super version:
To make an almost unbeatable Life Aura, use a Sanctuary Chip. Then on your next turn, use Life Aura. Note: It is very durable, but some enemies can break it. It will also wear off sooner or later. Try Black Bomb first and Shot Star.

Hint: Metalman V2:
You must first have the C-Slider. Go to Undernet 3. There are two warp points (not including the warp with the P-Code in front). Take the top one. Walk down the road that the warp point leads to. There is another road that branches off this road. Take that road and go straight to encounter Metalman.
Information in this section was contributed by Fastballfreak92.

Hint: Metalman V3:
Go to Undernet 3. Run around the area until you find him. Using chips to destroy his metal gears (like Gunsol1, 2, 3, Guardian, etc.) is recommended. Then, quickly use powerful Program Advances (such as Timebomb600, Lifesword, Flamecross3) before he uses Gear Change to bring back his metal gears. Also, when he goes to the side squares prepare to dodge his gears that ring around your area of squares like a boomer. Go to the center square immediately. Do not forget to dodge his metal punch.
Information in this section was contributed by Fastballfreak92.

Hint: Purple Skull Door Key:
Make sure you have at least 10,000 Zenny and the C-Slider before attempting to get this. Jack in from an outdoor location (preferably Netfrica). Work your way to Undernet 4 and look around until you see Solar Boy standing near a coffin. Solar Boy states that if he had a certain program he will be able to defeat the menace inside when it escapes. To get the program, travel to Undernet 2 via the Sharo area and talk to the Dark Navi who says "The chip is in Undernet 6". Work your way to Undernet 6 and look for a Dark Navi pacing back and forth. Talk to him and he will offer you the program for 10,000 Zenny. Bring the program back to Solar Boy, then an intermission sequence will start. After the sequence, look inside the now empty coffin to find the Purple Skull Door Key.

Information in this section was contributed by oFastballfreak92.

Hint: Shadesoul:
You must have all the six Souls and already have fought Bass. You also must have all the Evil Chips. Save the game before attempting this. Have Mega Man use the Dark Chips and unleash his Darksoul. Do this about three to five times. Then, keep it for a long time. You will notice on the picture of Mega Man (when you are virus busting) growing a fang. Note: You might have to save it, and if you do you cannot use the Soul Unison program Doublesoul.
Information in this section was contributed by Sabinocastillo59.

Hint: SP Navi Chips:
To get SP Navi Chips you must delete a Navi with an "S" rank. It is very difficult, but the best way is to use a Dark Chip in a regular virus battle repeatedly until when you start a battle you are already Dark. Then, leave the battle and go to the area with the Navi you want an SP chip of. Use a strong Dark Chip and defeat them as fast as possible. Note: You must get all SP chips and DS and regular Navi chips to open the door in Black Earth 1 (in the dark hole in Undernet 6; need all Evil chips to enter).

Information in this section was contributed by tai the cheat sender.

Hint: Easy standard chips:
To get all 150 standard chips easily, use the Chip Trader Special in Electown in H2 mode. The easiest way to get chips for this is to delete Mettaurs in Lan's doghouse.
Information in this section was contributed by demonsblade32.

Link up with a friend, select the "Compare" button, then select the "Library" button. All of the chips that your friend has but you do not will now be available in Higsby's chip order system. However, they will be very expensive.
Information in this section was contributed by shelby chase.

To collect all the standard chips, get the program Collect from the Bug Trader in Park Area Three for 42 Bugs.

Hint: Defeating Aqua Man:
Get chips that break panels on your side of the field. When Aqua Man tries to use his Bubble Bomb, it will fall in the hole and does not affect you.
Information in this section was contributed by Chrismasterx3193.

Hint: Defeating Cold Man:
Notice that Cold Man constantly puts down ice blocks. If you use Junksoul, you can send all the ice blocks he puts down back at him with Poltrgst for massive damage. Note: Cold Man is a patterned attacker; he will use the ice blocks repeatedly, so you can keep smashing him up.
Information in this section was contributed by emurater.

Hint: Search Bomb Battlechip:

Hint: Purifying Mega Man:
Use the following trick to purify Mega Man. There are certain conditions that must be followed; Mega Man cannot be fully dark and during this process, you must not use Dark Chips. The Dark Chip effects are as follows: after using a Dark Chip, Mega Man's color becomes darker; chips like Holy Panel and Sanctuary cannot be used (when stepped on, they fade); and bugs occur during battle when used. For healing: during battles, you must not use a Dark Chip; watch his color after ten to thirty battles (if done correctly, he will gradually become lighter); and after awhile, he will become the way he was before the Darkness. Note: the HP lost from the Dark Chips will still be lost, and If Mega Man is completely immersed in darkness, this trick will not work.
Information in this section was contributed by Marcus Hanna.

Hint: Blue Mystery Data:
Every time you defeat Duo, you can start on the next level. The viruses get upgraded and so do the Bosses. After the level 3, the Bosses and viruses stay at level 3.
Information in this section was contributed by romanater.

Hint: Locked folder code:
When your folder is locked someone who told you that he was supposed to fix it, go to ElecTown. Talk to the girl standing near the entrance to ElecTown Square. She will tell you she saw the manager of Jojomon Electrics nearby. Go back and find an old man near one of the stores in ElecTown. He will look at your PET and tell you he cannot fix it without a code. The code is "9651345".
Information in this section was contributed by Anygore2.

When you get an email about PET Maintenance, after defeating Dex and Gustman in the Dencity Tournament, leave the building and talk to the person in front of the building wearing a blue cap. He will install a new folder with weak chips in your PET and lock it so you cannot use your original folder with the good chips. When he leaves, he will drop a piece of paper. You will need someone to fix your PET. Go to Electown area 2 and talk to the woman standing next to the building. Then talk to the old man and he will tell you that you need a seven digit password to unlock the PET. The hints are on the piece of paper. Try one of the following passwords: "1863546", "7374262", and "9681345".
Information in this section was contributed by San Saelee.

Hint: Park Area Gate code:
When Lan's alarm from home sounds, he runs home to find that his mom is in his room. She has been sprayed with sleeping gas. She tells Lan that she heard someone typing on his computer. Check the computer. There is a message reading, "You've been warned, Lan. We can easily do much worse. If you don't want those you care for to get hurt more, bring the DarkChip to Park Area 2." Jack in and go to the end of Town Area 3, where there is a purple gate. After the short intermission, a work comes and battles you. Defeat him and he will be knocked out. Search him for the code to open the gate. The code you get is "AJEKDUR 2437561". It is encrypted. Decrypt it and you will get "RAEJDUK".
Information in this section was contributed by San Saelee.

Hint: Asteroid:
While in the asteroid and the big magnetic disturbance appears, press A as fast as you can to "swim" down. If done fast enough, you will go down and land once it goes away, and be able to continue.
Information in this section was contributed by Ivanbass.

Hint: Secret passage way in Undernet1 to a NetDealer:
When you get to Undernet1, go straight and you will walk under a dragon-like mouth and onto the escalator things on the ground. It will bring you to a square with three paths that you can take. Follow the one on the right. This path then breaks into two others. Again, take the one on the right. When you get to the end, there is a hidden pathway you can take by going up. It will lead you to a NetDealer.
Information in this section was contributed by San Saelee.

Hint: Secret walkway:
There is an island in Town Area 1 (the one with purple data). You can get there by walking on an invisible path, where the square with all the holes in it are. Walk to one of the edges and you will find the invisible path.
Information in this section was contributed by ewdrake.

Hint: Unlimited Zenny:
Jack into your computer at home and go towards the first door with the skull on it. When you go there, make sure you are doing a mission like the competition at the dome or something not in ACDC town. When you go there, you find a chip containing money. After getting it, jack out and do the same thing again.
Information in this section was contributed by Sean Faria.

Hint: Battle Navis from other version:
Link up with the other version of the game. For example, if you are playing Mega Man Battle Network 4: Red Sun, link up with Blue Moon. Go to the "Com." option at the main menu. Go to "Waiting Room". Go to "Reception". Send a Navi from the other game to yours. Then, go to Higsby's and enter in a free tournament so that you face that Navi. Then, beat the game. That Navi will now be participating in the tournament site it was in the other game (for example, Woodman in Eagle Tournament).
Information in this section was contributed by Zwwilderman.

Hint: Normal Navis and Heal Navis lose at Free Tournament:
In Free Tournament, watch the match (do not skip) between a Regular Green or Purple Navi and a Soul Navi (Roll, Guts Man, Search Man, etc.). There is a 90% chance that the Soul Navi will win.
Information in this section was contributed by DDRMarik.

Hint: Tournament winner:
Go to the free tournament in Higsby's shop and join. Note: You must have Navi data in there. When the CPU players fight, wait for a Navi to hit the low HP. If your friend had UnderShrt on, wait for 1 HP. When the weak Navi is about to lose, quickly press Select to skip the battle. The loser will suddenly win, even if it was impossible. Note: This does not always work, but is a great way to get secret chips from weak Navis.
Information in this section was contributed by Manuel Miramontes.

Keep pressing B while running to avoid getting into lots of battles like you do when you just run.
Information in this section was contributed by Parker Dolezal.

Dodge the conveyer belts in Sharo and you will eventually see the Water God near the top of the Sharo area. Go up the conveyer belt pointing to the Water God. Get the Water God. Go back to the Netfrica area and talk to the official to complete the quest.

Hint: Rescuing Roll:
When you pass the Eagle tournament prelims and defeat the first competitor, your next opponent is Roll but she will get kidnapped. The kidnapper takes her to Park area 3, then goes shopping. To find the key to the door where he put Roll, you must go to ACDC area 2 and defeat his virus. He then gives you the key.

Hint: Saving Chisaio:
In Red Sun, Lan faces Dex. After seeing the results, Dex comes up asking where Chisaio is located. You will get an email that reads "OMIQR LANUE DNSA". Decode it to get the message "Old man in square". You will get a memo reading "!si ivan neerg eht eerht aera nwot ni". When read backwards, it comes out to be "In town area three the green Navi is". This on says "Might try looking you inside flowers of the vase". Look at the flowers at Den Dome and Chisaio will e-mail you. Go to the squirrel in the park, and the message is chipped off. Go where you met Shademan and talk to the Navis. One has a battle to win. Then, you must find five datas around the nat and go in front of the tower in town square. After fighting viruses, Chisaio will appear. Go to the dome to fight Dex.

Hint: Insane Robots:
When you take Mayl to the the park in Red Sun, you will end up having to fix some robots that have gone crazy. You need to jack into them in order to fix them. There are doors in each robot that are blocking your way to the off switch. The only way to get by the doors is to find and replace the missing data, as follows:
Information in this section was contributed by Cabal.

ToyRobocomp1 - Princess
Door 1. Mirror
Door 2. Big Tree
Door 3. MightyBl

ToyRobocomp2 - Wizdog
Door 1. Wzmonkey
Door 2. Magicsel
Door 3. GoodNose and Scratch

ToyRobocomp3 - Tinman
Door 1. War and Emotion
Door 2. Bird and Dance
Door 3. Toypart

ToyRobocomp4 - Dracky
Door 1. Gunsol and Crmscarf
Door 2. Otenko
Door 3. Sunlight
Door 4. Skylight and Taiyohh

Note: After the last door, you will fight Shade Man. The only way to defeat him is to use the Darkchips.

Hint: Dark chip warning:
Be careful if you use Dark chips whenever you can. Eventually Mega Man will be naturally black and you will always start with Dark chips (even during Boss fights); and even if you do not use one, you will still lose health. Also, you will not be able to use your Gunsol EX unless the DS takes over.
Information in this section was contributed by randy schoch.

Hint: Changing back from fully dark Mega Man:
If you use the evil chips such as Marasuma and Anubis a lot, eventually Mega Man will lighten to the point where you can unite again and use Gunsols. Unfortunately how many time you use it is unknown. Continue getting Critical Hits and "Full Synchro" (although you cannot see it) even when using Dark Chips will help.
Information in this section was contributed by Nicholas Muriel.

Hint: Do not lose life with Dark chips:
Use at least one Dark chip in every battle for about 500 battles. You will stop losing health every time you use a Dark chip. Note: If you stop using the Dark Chips with every battle, you will start losing health again when you begin using them again. Basically, you must never stop using Dark chips.
