Mega Man: The Wily Wars, known as Rockman Mega World (ロックマンメガワールド) in Japan, is a compilation released in 1994 by Capcom for the Sega Mega Drive.

It contains updated versions of the first three Mega Man (Rockman) games, Mega Man, Mega Man II and Mega Man III, originally released for the Nintendo Entertainment System in 1987, 1988 and 1990, respectively. Also included is a set of Mega Drive-exclusive bonus stages, collectively called "Wily Tower," unlocked after finishing all three games.

In the United States, it was released as a Sega Channel exclusive, although the box art of a proposed cartridge release has since been found. Said box curiously features an unusual (for the Mega Man series) MA-13 rating, although it's likely this was an error as the Sega Channel release was rated GA instead. Reportedly the game was put on indefinite hold in the US due to graphical issues[3].


In these games the objective is to pick a stage, navigate it defeating enemies along the way with the buster, and beat the robot master at the end of the stage. Once the player defeats the robot master you gain it's weapon to use on a different robot master. In layman's terms it's like a game of rock-paper-scissors. Once you have defeated all the robot masters the player goes to the Wily stages where the final set of levels awaits. Occasionally the player will get extra power ups to assist you in your game play such as the Magnet Beam, Dr. Light Items, and Rush. A opens the menu to choose a weapon, B fires the weapon, and C jumps. In Mega Man 3 and the Wily Tower (see below), Down+C slides. Some weapons, such as Mega Man 2's Metal Blade, can be shot in a particular direction by holding the D-pad while pressing B.

After beating the three main games the player unlocks the short game Wily Tower. Wily Tower only has three robot masters, which the player does not gain a weapon from, and then four Wily stages. At the beginning of each robot master and the Wily tower the player chooses weapons and items to take with them from the three original games giving the player an interesting twist on having weapons from different games.

The robot masters in Wily Tower actually share a similar origin to things in the Chinese epic Journey to the West. Buster Rod.G is based off Sun Wukong (called Son Goku in Japanese), Hyper Storm.H is based off Zhu Bajie (called Cho Hakkai in Japanese), and Mega Water.S is based off Sha Wujing (called Sa Gojou in Japanese).

Some experienced players of the original NES games may notice that the game speed is slightly slower thus making the game in some cases easier, but other parts may become more difficult due to different timings.


  • The player is able to choose from any of robot masters to start from. This is just a general list of the levels.
  • No weapons are gained from the Wily Stages.

  • Buster Rod G
  • Mega Water S
  • Hyper Storm H

Artist Keiji Inafune claimed that the development of the game was outsourced and rather slow going. He described the debugging procedure as "an absolute nightmare", even helping out in process himself as he felt bad for the person in charge. "It was so bad," he recalled, "I found myself saying, 'I can't believe we've made it out of there alive.'" The team later questioning whether the nightmare was "truly necessary", led to changes in procedure to try and avoid similar situations in the future.

With the theme of the game being the novel Journey to the West, Inafune stated that while drawing the three new boss characters he "tried to take the flavor of the theme and give it that Mega Man twist." Other than these characters, Inafune's only other illustrative contribution to the game was the depiction of Mega Man and Rush on the cover art. The soundtrack of The Wily Wars, composed by Kinuyo Yamashita, consists of 16-bit versions of the original Mega Man musical scores, as well as new songs for the Wily Tower portion of the game.



  • In all games, shots are limited to one shot every few frames of animation. In the originals, players could fire weaponry on every other frame.
  • The controls in these versions of the games seem a little tighter than the originals, though Mega Man himself seems to have a slight delay before moving because he is able to do sidesteps.
  • A number of weapons now have a noticeable "can't move" delay after firing, such as the Items from Mega Man 2 or the Shadow Blade from Mega Man 3.
  • All three games now have a "save game" feature. However, the "password" feature was removed from Mega Man 2 and 3.
  • At several points, the game suffers from very bad slowdown. However, for less-skilled gamers, this can be a positive effect; because the Yellow Devil's stages in Mega Man and 3 suffer from it the most, as does the battle with the Wily Machine in Mega Man. This makes those boss battles much easier.
  • However, running the game on a system (or emulator) with an overclocked M68000 chip will run the game at full speed regardless of how much is going on at any given time. This would normally make a Mega Drive game very unstable, but has no negative effects on The Wily Wars due to how it was programmed.
  • The European version has slowed down music due to it running on 50 fps instead of 60 fps like the Japanese version.
  • In general, despite their names, the games are based more closely on the Rockman versions than on the Mega Man versions; most notably, Normal Mode is absent from Mega Man 2.
  • The Title Screens are also based on their Japanese versions, but with "Rockman" changed to "Megaman".

Mega Man

  • While the original Mega Man's boss select screen simply showed the Robot Masters' in-game sprites as icons, the Wily Wars remake uses new mugshots to match Mega Man 2 and 3, and for Dr. Wily, his in-game sprite for an icon is replaced by the Dr. W logo.
  • Cut Man is much tougher in the remake than he was in the original game. Mostly due to the fact that his flinch is much less intense and the Mega Buster deals a third of the damage that it would normally do.
  • Bomb Man is similarly more difficult. If you got near him in the original, he would normally jump away, but in Wily Wars, he instead opts to get close to you.
  • Power-ups do not reappear when leaving the screen and coming back.
  • The Pause/Unpause glitch has been fixed.
  • Some Robot Master AIs have been slightly modified.
  • Normally during invincibility frames you can still die from spikes. This is fixed in this version to be like all other Mega Man games.
  • The gravity bug when falling off the Magnet Beam and the platforms in Guts Man's stage and Wily Fortress 4 has been fixed.

Mega Man 2

  • Mega Man 2, similar to its original Japanese release, Rockman 2: The Mystery of Dr. Wily, does not have a difficulty selection. Instead, it only plays on "Difficult".
  • Quick Man is much slower in this version, though he no longer takes two damage from Mega Buster shots as he did in the "Difficult" mode or the Japanese version of Mega Man 2.
  • Flash Man also takes one damage from the Mega Buster instead of two, like he did in "Difficult Mode."
  • Some Robot Master AIs are slightly modified.
  • Robots and robot masters have invincibility frames where they can not be damaged. This is not true for robots that die in one hit.
  • When the player loses all of their lives, they no longer lose all their E-tanks. In the original, continuing meant forfeiting any and all E-tanks remaining in the inventory, preventing players from farming the start of Metal Man's stage. Now it is possible to do so.

Mega Man 3

  • The grey tones on Proto Man's sprites have been changed to white.
  • Proto Man's "shadow" sprites from the ending are found in the game data, however, Capcom decided to just use a "shadowy" palette on the original sprites instead of those.
  • While not a difference, neither Proto Man nor Break Man have been resized like Mega Man and the Robot Masters have. They don't have any additional frames of animation, either.
  • On the Weapon Select Menu, Rush is now blue instead of red. (This also happens in Wily Tower.)
  • The Wily Castle map screen music has been shortened from its original tune. (Incidentally, the extended theme wasn't accessible in-game anyway.)
  • Like the first two games, some Robot Master AIs are modified.
  • Robots and robot masters have invincibility frames where they can not be damaged. This is not true for robots that die in one hit.
  • Magnet Missile's have odd behavior; sometimes they do not "home" (right turn up or down) correctly. Hard Man and the Doc Robot Metal Man are much more difficult due to this fact.
  • The crocodile-like traps in Hard Man's stage activate quicker than the original game, so do other traps.
  • Controller 2 cheats from the NES game have been removed.
  • Early Rush adapter glitch removed.

Credits (or lack thereof)

The original three games have their credits screens still in place, but after beating Wily Tower there is actually no credits listed; just a cutscene and a list of all the Robot Masters. There is also no list of credits in the manual either.

The only source of credits available comes from the worklist of freelancer Kouji Murata[4], who handled all the sound aspects (sound driving, sound porting, composition and arrangement and sound effects) for Mega Man III and IV (Rockman World 3 and 4 in Japan). He credits himself for Sound Effects in The Wily Wars and refers to a "Yamashita-san" when crediting the music.

Because he worked through Minakuchi Engineering from 1990 to 1992 (during which Mega Man III was created) and continued to work on the Rockman World series up until late 1994 as a freelancer, he is most likely referring to Kinuyo Yamashita of Castlevania fame, as she was associated with Minakuchi Engineering around that time. This is because Yamashita was contracted through the company circa 1995 to compose the music for [the SNES version of] Mega Man X3 (Rockman X3 in Japan). Additionally, the two had previously worked together on Famicon Disk System title Arumana's Miracle.
