Hint: 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.

Hint: 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).

Hint: 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.

Hint: Adding chips to your folder:
Press A on any chip on your sack, then press Left and exchange the chip.

Hint: 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.

Hint: 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.

Hint: School network passwords:

Door 1: 09
Door 2: 30
Door 3: Random
Door 4: Random
Door 5: 15
Door 6: Random
Door 7: Random, but also requires Teacher's password.

Hint: 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.

Hint: 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.

Hint: 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

Hint: 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.

Hint: 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.

Hint: Muramasa:
Put at least three Navi chips, five Cannons, and twelve of your choice and you should get that chip.

Hint: 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.

Hint: "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.

Hint: 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.

Hint: 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.

Hint: 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.
