Get Navi chips
Defeat Woodman, Sharkman, Skullman, Protoman, Fireman, Elecman, Numberman, Gutsman, Iceman and Colorman over busting level 5 to receive their own battle chip with one of their most powerful attacks.
You can actually get Navi chips in the trading machines in Higsby's shop. For example, you can receive a Roll3, Woodman1, Protoman2, Pharoahman1 or Sharkman2 chip just by putting in chips. However it seems that it will only give these chips if you have them already.
After you defeat a Navi and get their chip once, fight it again later. If you defeat it without taking any damage, you should get either an extra of their chip or a stronger version of their chip.
If you want to get Navi or any other chips, go to Higsby's Shop. Go to the Blue Trader and save. Then, put in 10. If you get the one you want, leave, save, and try for another one. If not, reset the game and try again.
Anubis chip
You do not need to complete the game to get the Anubis battle chip. You can also get it in the chip trader.
Muramasa chip
This chip is also attainable through the 10 chip gambler, but takes many tries.
Popup chip
In a few areas on the net you will find the Popup enemies, who resemble some sort of dog. They only have 10 HP, but every time you hit one, it will drop into its hole and pop out of another one. The more HP taken away, the faster it will go back into its hole. It is virtually impossible to defeat by the time it has at most 3 HP remaining, because when it goes into its hole, it will escape. An easy way to defeat it is to use the Anubis chip. You have to have completed the game at least once so you can get the Anubis chip from Pharoman. When you fight the Popup and have an Anubis chip to use, just set it down. The Anubis continuously depletes the enemy's HP (even multiple at a time). The Popup will automatically get hurt when it comes out of the hole. After it is defeated, you should get the rare Popup chip, which makes you invincible for a turn when not attacking (same as the Dropdown).
Get rare or new chips
When you get to the part of the game where the Higsby guy from the school incident has a business as a chip salesman (in front of the gates of the school), go inside and save your game next to the chip trading machines (the ones that resemble candy or mini-toy dispensers in real stores). You can now freely trade 3 or 10 chips for another one, depending on which machine you use. If you do not get a chip you want, turn off the game, turn it back on, and resume from your save. Repeat the chip trade until you get the one you want, or get a rare one.
Stand in front of the 10 chip machine and save the game. Continue using chips until you get the desired chip. If you do not get it, turn the game off and restart. Keep repeating this until you get what you are looking for.
Adding chips to your folder
Press [A] on any chip on your sack, then press [Left] and exchange the chip.
Challenge Arena
Get the first memo and at the end of the first WWW site, take a right before the next red W. Continue until you reach another access. Continue and talk to the person at an intersection. He should tell you some strange information, but you will see a door with a "?" on it. The next one will have a different challenge, and then another. Along the way there are web merchants. Once you get through, there should be two men that are almost parallel, this is the Challenge Arena.
Power Plant
Once the subway starts working and you go into the second town, on the first block go up and turn left (do not cross any sections). There are various sections to stop (save after every battle). To get into the power plant finish the cross section and go to the park in your town. You will meet your dad who invites you to a party with mom. Once you are there, the power goes out. You will exit the dining room and go down the laundry chute.

Advances
Advances are when you pick a particular combo of chips. You can learn two of them by talking to the kid besides the Numberman sign in Higsby's Chip Shop and the little girl in Block 3 of Dentown, in front of the Print Shop. Advances can be three of the same chip in alphabetical order. This usually gives a "z ?????" which lets you use your chip as many times as possible in five seconds and activates an Invisi1 type move.
Guts Shot Advance
Use Met Guard G, a Dash G, then Guts Man3 G in that order. Gutsman will appear on the panel, grab Megaman and throw him at the enemy in front of him. This takes off 500 damage.
Program Advance
This program mixes different chips and makes a stronger one. Note: It will not harm the game.
Zeta-Cannon 1: Cannon ABC or Cannon BCD
Z-Cannon 2: Hi Cannon GHJ or Hi Cannon HIJ
Z-Cannon 3: M-Cannon KLM or M-cannon LMN
Z-Arrow: Tri-Arrow CDE
O-Cannon 1-Cannon ABCDE
O-Cannon 2-Hi-Cannon HIJKL
O-Cannon 3-M-Cannon KLMNO
Lifesword1: Sword A, Widesword A, Longsword A (in that order)
Lifesword3: Fireblade F, Aquablade F, ElectricbladeF (in that order)
Ultrabomb: Lilbomb O, Crosbomb O, and Bigbomb O (in that order)
Program Advance 2X Hero
To get the Program Advance 2X Hero that does 400 damage use FighterSword B, KnightSword B, HeroSword B, and Protoman3 B in battle. Mega Man and Proto Man will be on a panel, charge their weapons, fire, and hit all enemy panels. Try using this on Bass.
Bug Style bugs
Some of the bugs that you may have when you get Bug Style are good:
Get 10 chips at the chip selection screen.
Invincible for a while.
Barrier.
Your Mega Buster might do 5 damage each time you hit an object.
Bad bugs include:
Lose health when you are selecting chips.
Lose health when you are battling.
Move up or down automatically.
Mega buster will not shoot once in awhile.
Better chance of encountering a Net Navi
When you are on the Internet at Lans or someone else's computer looking for a Net Navi, fight the same enemies in the exact same locations on the 3 x 3 panel three times in a row. You should encounter a Navi in the next battle 70% percent of the time.
Navi Master
Finding the Navi Master takes quite some time. Below is the list of clues and where they lead you. Note: They may not be in order.
The first clue leads you to the board outside the Marine Harbor Station (the restaurant board).
"The jug past the four cedars" leads you to Okuden Dam. Talk to the Official on the dead end.
"Big Bird Brain" leads you to the cockpit of the plane. Check the monitor near the door.
"Place that overlooks many cultures" leads you to the top of Netopia castle (where Knightman was located). Again, talk to the official.
"Coffin of things cast away by humans" leads you to one of the dumpsters in the alley in Netopia.
"Cyber forest, object of treasury" leads you to where Chnge. Bat was located. Talk to the Navi.
"A thing that plays a tune" leads you to Mayl's piano. Jack in and talk to the purple Navi in one of the corners.
"My natural parents" leads you to Lan's dad. Talk to him and the battle begins.
You will have to battle the V2 of the Navis you battle by talking to their operators. They are as follows, again not in order: Gutsman, Gateman, Snakeman, Toadman, Thunderman, and Protoman.
Muramasa
Put at least three Navi chips, five Cannons, and twelve of your choice and you should get that chip.
Defeating Bowl Man V4
Use Ice stage to freeze the ground in order to increase electrical attacks. Then, use Sensor 3 in the middle line which should hit Bowl Man several times before it fades. Then, use Plant Man V3 or V4. He should be dead or almost dead at least.
Defeating Protoman
Get Bstr sword and press [A] to activate it. Every time Protoman comes close to you, press [B].
Defeating Shark Man
When fighting Shark Man, he will hide under the tiles on his side. His shark fins will be moving up and down their columns. To find him, use an attack that damages the entire enemy area, such as Ice Man. The attack will hit all of the fins and do damage to whichever one is Shark Man.
Defeating Wood Man
When fighting Wood Man, he will sometimes grow a tree. After a few seconds, the tree will drop an apple and disappear. If Wood Man lands on the apple, he will regenerate health. Before he absorbs the apple, if it is on the column closest to you, use a Steal chip so that the apple is on your side of the screen. If you absorb the apple, you will gain health.
Encountering Bass
To encounter Bass from the classic Mega Man games, get 174 battle chips in your library. This is all the chips except for the one he drops, which is the Life Aura. Then, go to Internet area 16 where the two men are standing almost parallel. Walk around (it may take a while) and sooner or later you will encounter Bass. Put all the Recover 300 chips you have in his folder, as he is very difficult.
Encountering Fire Man
After you defeat Fire Man in the oven, he is going to be in your Net. Go on the normal path until you reach a two way path. Go forward and follow the path until you reach another two way path. Turn right and follow the normal path. When you reach a two way path again, go left. Follow that path until you reach a two way path. Go up and follow that path to a dead end. Fire Man will be at the dead end.
Easy S busting level
Use a Navi chip. When you use it, the background goes black and time freezes. When your enemy is destroyed, it should say S Busting Level, and your time will be in the milliseconds.
Dodge
Use the following trick when fighting either the Gaia Knights (Rock monsters with big hammers ) or the final Boss (World Virus), when they use an attack that explodes on each three column of squares. For example, when the Rock monster smashes his hammer on the ground and sends a shockwave towards Mega Man, when Life Virus uses the Sky Flame and it charges towards you. Just when it is on the row in front of you, wait for a split second then move forward to the row of three it was just on. You will dodge the attack.
Easy money
After completing the game, go out the school gates and go to the right (not Lan's right). There will be a man at the end of the wall who says that he lost his money. Go to the place where you fought Stoneman in the net, and there will be a purple man. Talk to him to fight him. After defeating him, go back to the man at the wall. He will give you 10,000 Zennies.
Easy Bugfrags
Select a 100barr as your regular chip and jack into Dex computer. GutsStyle (10 ATK points) is the best style for this. The enemies are Cannondumbs, Metataur, and some times a Spiky. One countering gives one Bugfrag, two counterings gives three Bugfrags, and three counterings gives eight Bugfrags. This is also useful for evolving styles.
Secret area in Sal's P.C.
Take the normal path until you reach a two way path. Take a left turn and follow the path until you reach another two way path. Take a right turn until you reach a two way path. Go down until you see a dark gray spot. Walk on it and take a right to enter the secret area.
"All your base…" comment
Check ElecMan's stage (where your battery is dying). Talk to all the civilian programs, and you will find that some are evil. One of the evil ones says CATS' famous line, "All your base are belong to us!", immediately before attacking.
Getting dressed comment
Before you defeat Stoneman and unblock the Metroline, talk to the boy running around outside of Mayl's house. He will say "Mayl and Dex and them just got back!". If he does not say this, talk all the people in the Metroline station and return. Go into Mayl's house and go upstairs. Go behind the ladder and stairs that you cannot go up. Mayl should be there. It is very difficult to see her. Talk to her and she will say similar to "I'm getting dressed, get out of here!" After that she will say "Quit looking! You pervert!".
Mini-quest
After you defeat Ice Man, go to the Waterworks. In the back of the room in the northwest corner is a man next to a soda machine. Talk to him and he will say that the machine is broken, and for you to jack in to fix it. Do what he says and talk to the purple robot in the middle to face three viruses. Defeat them and jack out. Talk to the man and he will give you a Repair G chip.
Mario and Luigi reference
At the Metroline Station in ACDC Town, look behind the guard by the far wall. You can see a picture of Mario and Luigi in a Metroline Car.
Pokemon reference
In Yai's House, there are various Pokemon-related items, such as a Gengar doll next to her phone and an Igglybuff on the television in her room.
Vile reference
Go to the Higsby shop (after you defeat him and go to the next day after class). Go to the back, where you will hear Mr. Higsby saying that he got some new chips. You will see a poster of Vile from Mega Man X.
Glitch: Walk through cars
Go southeast of ACDC town and keep an running in the middle of the road. If done correctly, the cars should pass through you.
