This is certainly the easiest of the GameBoy series, perhaps even the easiest Megaman game, period! I'm not sure I even need a guide for this one. Oh well, I guess it's just for completeness sake.
Like in the first GameBoy game, I'll probably surprise you with my robot master to fight first; Crashman. He's a mega-wuss in this game; his Crash Bombs are smaller and slower, plus Megaman can slide in this game, so they're a cinch to dodge. Also, you get Rush Coil after beating him. You get Rush Marine after beating Metalman and Rush Jet after beating Airman.
The first part of this stage is almost exactly like MM2. Tellys to start off with, then the track platforms.
At the halfway point, things start to change. Hop down the hole and veer left for a large health capsule. Then, keep to the right to avoid the Shotmen that inhabit the rest of this shaft. Move to the left at the bottom, though to avoid the spikes.
The next spot has a few pits to jump with Tellys flying at you. Just take your time, and make sure you don't collide with one of those things in mid-jump.
Near the end, you'll find three ladders. Take the one on the right for an Energy Tank, the one in the middle for a large health capsule, and the one on the left to continue to the end of the stage.
Crashman: Like Elecman before him, Crashman is so much easier than his NES counterpart. He has the same pattern; runs back & forth, jumps and fires a Crash Bomb when you fire at him, but he's much slower. You should have no problem sliding to avoid the bombs. Like in Megaman 2, he's weak against the Air Shooter, but it does nowhere near as much damage as before, plus it may be deflected by a falling Crash Bomb.
You begin with a freefall down a spike-filled shaft. It's not that bad, though, since Megaman falls a bit more slowly in the GameBoy games.
You'll now cross a familiar section with metal smashers and moles, similar to the NES version. The corridor is much tighter, though, so be ready to slid past the smashers as soon as you can.
You'll need Rush Coil to get the 1-up near the end of this stage.
Metalman: Another wussified robot master. Metalman has a similar pattern as in the NES game, but he always throws 2 Metal Blades now when you shoot at him, as opposed to 1-3 Blades before. Knowing this, you should be able to defeat him while taking minimal damage. Crash Bombs work great, wiping him out in just four hits. Just aim carefully, since the Crash Bombs have very limited ammo.
Most of this stage is very much like the original stage. The beginning is filled with Battontons and Robbits, plus a Flame Dog. The end is another stretch with Cooks running amuck.
The only different area is the midpoint. The bottom is filled with water, and the top is a series of platforms filled with Metools and the shield cannons and spikes coming out of the ceiling like in Needleman's stage. If you have Rush Marine, though, you can just ride through the water, and bypass it completely.
Woodman: This guy was dumbed down like you wouldn't believe. His attacks do a lot less damage, and you can fire right through the leaves on his Leaf Shield, so you can still hit him while the shield is up! Just sling a few Metal Blades at him and this fight will be done within 5 seconds.
This stage is almost a complete copy of the NES stage. They just put the Lightning Lord section near the end.
Airman: Your slide ability makes it easy to avoid the Air Shooter, that and the fact that the tornadoes move slower. Just hit Airman with the Leaf Shield when you have a good shot. In this game, if a leaf hit a tornado, it'll get blown away, but not the whole shield like before.
Once the first four robot master are toasted, you'll go to Wily's fortress, where you're instantly presented with four more, in the form of a teleproter room. Each teleporter takes you to a different stage.
As with the rest of the stages, much of this stage is the same as the NES game, with only a few small changes. Just look at my Megaman 3 review for more info.
Needleman: Of all the robot masters, Needleman will probably give you the most of a fight, but not by much. He's weakest against Top Spin, but Air Shooter also works great. Don't use it when he's firing the Needle Cannon, though, since they'll block your shots.
Another point for lazy stage designers. Again, the stage is nearly identical to the NES stage. Just look for an easy Energy Tank where you fought Protoman.
Magnetman: He fights about the same as the NES version, but he doesn't seem to take as much damage from your buster as before. Oh well, the Needle Cannon will take him out quickly.
The scrolling technique doesn't work on the Havsubees this time, but the Leaf Shield can easilly protect you from Chibees. As an extra tip, the Leaf Shield doen't use energy until you fire it, so just block the bees with it, then switch to another weapon, and you won't use any energy!
Metal Blades work best to hit the Mecha Monkeys without being stomped on.
Hardman: Same fight as the NES game. Use Magnet Missiles on him, just don't fire when he fires his Hard Knuckles, or the Missiles will seek them instead.
The first part of the stage has a water section with appearing/disappearing platforms, but that's easilly bypassed with Rush Marine. The rest of the stage is the same at the NES version, more or less.
Topman: Again, this is the same as the NES battle. Just beat him down with Hard Knuckles when he isn't spinning.
Quint: You'll fight Quint after defeating all of the robot masters, and boy is he easy. He just bounces in place on his pogostick, tossing debris out at you, then jumps to another part of the room where he repeats his pitiful pattern. The pogostick will rebound your shots, so aim for the head. Crash Bombs and Hard Knuckles do the most damage, but you should be able to defeat him easilly with just your buster.
There's really nothing new in this stage. It's just a rehash of everything else you've encountered in this game. It's not even tricky. If you can't get through this stage, shame on you.
Dr. Wily: Wily is pretty easy, but you may still want an Energy Tank on hand, just in case. He sure looks pathetic, huh? Anyways, as always, you want to aim for the cockpit. None of your special weapons work, so stick with your buster. Quint's Sakugarne does a lot of damage, but you may end up killing yourself trying to use it on him. There are a total of three phases of Wily's machine, but they're all rather easy and have an simple pattern.
