Lan's Home[edit]
The game will start with Lan waking up from sleep after being warned he'll be late for school. You'll need to pick up the PET in the right corner by pressing 
. Afterward, you'll get two new emails:
- NetNews - WWW Crime!
- Dad - Sorry!
Open dad's email for a CrossGun C chip. There's nothing more you can do here so go downstairs. Lan's Mom has prepared breakfast for him on the table. Check the plate on the table for a Recov10 A chip. You'll find Mayl waiting outside and automatically walk with her to school. She'll mention that people's ovens have been catching on fire and wonders if it's a WWW virus.
School[edit]
Speak to Dex, the kid with a green shirt, in the left corner. He'll challenge you to a NetBattle, but the school bell will ring. Class will start and Ms. Mari will give a lesson on virus busting using Mettools 
. Jack into Lan's PET by pressing 
.
For the first lesson, you'll fight against two Mettools, or Mettaurs. Ms. Mari will explain how to send chip data and what the various UI elements mean. You have a choice of 5 chips:
- Cannon A
- MiniBomb L
- Cannon A
- Shotgun N
- CrossGun J
If you select a Cannon chip, you can select the other one as well. Ms. Mari will then explain battling and additional UI. Defeat the two viruses.
The next lesson will have three Mettools. Ms. Mari will explain about support chips. Select Steal and then WideSwrd in that order. Steal will turn the closest enemy column area into yours and WideSwrd attacks the column in front of MegaMan. Use these two chips to defeat the front two viruses, then weaken the last one with your buster and finish it off with a battlechip.
The last lesson will also have three Mettools. Ms. Mari will explain chip adding. Select the ADD button and battle for one turn. When you return to the chip selection menu you'll get five extra chips to choose from. Defeat the three viruses. Once they are defeated class will be over. You can challenge Dex and his GutsMan if you want, he's easy to beat but you won't get any reward though. Leave the classroom and you'll get two new emails:
- Dad - PowerUp!
- Ms.Mari - Class notes
Dad's email mentions he has a PowerUp for MegaMan, but it's too big to send through email. Ms. Mari's email explains that chips don't run out when used and to jack out press . Try jacking into Lan's doghouse and get the mystery data that's up to get a Shotgun K chip. It's a good idea to grind here for a bit, the Soniwave chip dropped by the red Mettool is especially useful early on, so try and get as many as you can. The first default chips you should get rid of are the Recov10 chips and the X-panel1's. After you're done jack out and head into Lan's home.
Lan's Home[edit]
When you return, you will find a man from NetSafety is checking the home control panel. Go upstairs to Lan's room and jack into the computer. There's isn't much to do in Lan's Computer so go through the portal to Internet 1.

Move forward and you will see Glyde, Yai's Navi. He tells you that one of Yai's programs is lost and gives you @Yai, which allows you to access Yai's network. Take the above path. Along the way you'll find green mystery datas which you can pick up for random goodies. Unlike blue and purple ones they come back every time you jack in. You can't open the glowing door with a skull, so just leave it alone for now. If you keep going left you'll eventually run into a glowing circle with the words ACCESS on it, which is Yai's Portrait, keep this in mind since you'll have to come here very soon. Follow the fragmented bridge and you'll find a net merchant along the way. He sells:
| Item | Price |
|---|---|
| HPmemory | 500z (1000z) (2000z) (3000z) (5000z) |
| PowerUP | 2000z (5000z) |
| WideSwrd K | 1000z |
| Spreader I | 1000z |
| Hammer A | 2000z |
| Recov50 C | 2000z |
| Cannon C | 3000z |
The only useful things he sells are the HP memories which increase your maximum HP by 20, and the PowerUP, which you can spend under the MEGAMAN menu to increase either attack, which increases the attack power of your buster by 1, rapid, which increases the speed, or charge, which will allow you to hold 
to charge up your buster for a stronger attack; don't bother with the battlechips since you can find them for free not too far into the future.
You should get the PowerUP first and preferably spend it on attack since the charge won't be useful until much later into the game. Speed is pretty much useless so don't bother with that until you've maxed out attack and charge. Don't worry if you can't afford anything yet, you can always come back later when you have more zennies.
Continue past the merchant and talk to the lost program here. The path up ahead leads to Dex's portrait and internet area 2, both of with are currently blocked off, so head back to Yai's portrait.

Talk to Glyde to tell him where the lost program is and he'll give you a Spreader I chip as a reward. You can explore the rest of the area picking up the mystery data, but don't bother following the path all the way since it leads to a dead end. Get a few Dash chips if you want then jack out.
