This page details one or more prototype versions ofMega Man X2.

TwoJapanese prototypes ofMega Man X2 were found and dumped by C. Davis in 2018:

• The first prototype, hereafter referred to as the "later" or "newer" build, wasreleased by Rockman Corner on July 21.
• The second prototype - the "early" or "older" build - was purchased through the funding efforts of Revenant, GoldS, and C. Davis, then released by TCRF on October 6.

Note that the "raw" version is a pure, unmodified ROM dump from the sample cartridge. Itwill not work on emulators, since the header info hasn't been finalized yet. Please use the "hacked" version, which fixes the header, to run this prototype on an emulator.

Certain emulators that don't properly emulate the Cx4 chip will exhibit incorrect behavior while trying to run these prototypes. As of this writing, ZSNES and Snes9x will exhibit the following errors:

• Incorrect positioning of sprites. This includes stage select previews, Sea Canthller, Magna Centipede's rotating tail attack, and Morph Moth's cocoon.
• Wireframe models either crashing the emulator (in the case of ZSNES) or not displaying properly but having their hitboxes intact (Snes9x).
• Other Cx4 effects breaking, e.g. Morph Moth's laser.

While bsnes will accurately display graphics and position sprites, it seems to freeze at certain points. The most stable emulator available at the moment isbsnes-plus.

Debug Features

Global

At any time, holdSelect on Controller 1 to temporarily freeze the game. You can also pressStart on Controller 2 to toggle freezing the game.

HoldSelect on Controller 2 to slow the game down to 1/3 speed.

Gameplay

All of these are done on Controller 2.

• A + Up/Down - Adds / removes lives (with appropriate sound effects!).
• B Button + Up/Down - Warps to the next/previous checkpoint in the stage.
• L + Up - Refills player's health as long as the two buttons are held.
• R + Up/Down - Changes the player's checkpoint without warping to it.
• A + X - Pressing simultaneously while holding any button on the D-Pad toggles armor pieces:

• Up - Leg Parts.
• Down - Body Parts.
• Left - Arm Parts.
• Right - Head Parts.

• B + Y - Pressing simultaneously toggles invincibility.
• A + B + X + Y - Pressing simultaneously kills X.

Music

Morph Moth Stage

Morph Moth's track ends slightly differently, and the sound mixing overall is a little off compared to the final.

Boss 2

The regular boss theme is missing several sound channels for some odd reason. Additionally, there is no separate track for when the boss first appears, this track just plays early compared to the final.

Another Boss 1

The X-Hunter intro music (used for the X-Hunter base fights and for the Gigantic Mechaniloid) is completely different in the prototypes.

Unused Track

The track occupying slot25 in the later prototype only isthe unused, unlinked track found in the final ROM. In the final game, this was replaced by the prologue cutscene's music.

Pro Action Replay (PAR) code06880525 will replace Morph Moth's track with this one.

Unknown Track

Occupying slot1A (the regular boss theme in the final game) in the early prototype and slot1D (the stage select theme in the final game) in the later prototype is a very strange unused track of unknown purpose. Pro Action Replay (PAR) code0688891A will play this track in Morph Moth's stage in the early prototype, while0688051D will play it in the same stage in the later prototype.

Missing Tracks

The following tracks are completely absent in the early prototype:

The following tracks are completely absent from both prototypes:

Enemies

HP Values

Most enemies in the game have HP differences between the two prototypes and the final game. All but two were reductions; the two that had their HP increased were the Bar Waying (to keep them blocking the player longer) and the Disc Boy 08 (to keep them from being destroyed by one single fully-charged X-Buster shot).

Damage Dealt

Like the enemies' HP values, these were mostly reduced in the final game, though there are a few that were either increased or swapped around.

Miscellaneous

• Almost all enemies are missing sound effects in the early prototype. It's actually quicker to list what enemiesdo have their final sound effects assigned:

• Blecker (landing only)
• Jelly Seeker
• Raider Killer (landing and firing plasma shots only)
• Rideloid-G
• Rightod

• Similarly, the following enemies use temporary sound assignments in the early prototype:

• Cannon Driver (firing - uses X-Buster sound effect)
• Raider Killer (firing lasers - uses half-charged X-Buster sound effect)
• Slidame (grabbing - uses X's damaged sound effect)
• Tiranos (firing - uses X-Buster sound effect)

• The Barrier Attacker can be frozen by the Crystal Hunter in both prototypes, something that's required to do to get across a spike pit in X-Hunter 1. They're unaffected by the Crystal Hunter in the final game.
• Croak Hopper are bugged in that their hitbox lingers while they're exploding. This is likely due to their unique destruction animation wherein the big frog explodes first, then the little frog after that.
• Fisherns move twice as fast in the later prototype.
• In the early prototype, Scrivers will continually drill in the air until the player gets close enough, at which point they'll jump towards the player. In later versions, the Scrivers will stay in place until the player gets close enough, at which point they'll hop towards them. Then, if the player is close enough, they'll try to drill into them.
• Weather Crystals have 20 frames of invincibility after getting hit in the early prototype and just 2 in later versions.

Script

General Notes

• The early prototype only has new dialogue for the Light Capsules. Everything else is fromX1.
• The later prototype's draft doesn't include the cutscene that plays after defeating all Mavericks without collecting all of Zero's parts, nor the "Repairing Zero" cutscene that plays when the player exits a stage for the first time with all of Zero's parts.

• Dr. Light still uses a dialogue picture in the early prototype.
• There are no full stops (。) in the early draft.

Graphics

Protos	Final

The hiragana + katakana character set is identical to the first game's set in the prototypes. The final game redraws each character to add a shadow, then adds a few letters and numbers into the set.

Protos	Final

Most of the characters in the game's alphanumeric font were tweaked in the final game. The question mark is particularly different.

Later Proto	Final

The early prototype has no large font, but the later prototype does. UnlikeX1, the large font inX2 has every letter of the English alphabet. The S, X, and Z (all new to this game) were touched up in the final version.

Prologue (Unused)

きょうも　また　エックスは　ハンターきちからの しれいをうけイレギュラーが　せいぞうされていると　される

きょうも　また　エックスは　ハンターきちからのしれいをうけイレギュラーが　せいぞうされていると　される

This is a formatting change; the first line in the early draft is one character too long.

しかし　それはエックスにとってあらたなたたかいへのプロローグでしか　なかった・・・

The last line of the prologue text isn't in the early draft.

   ロックマン エックス　「カウンターハンターへん」

        ロックマン Ｘ２「 バーサス　カウンターハンター 」

X-Hunters Intro

やつが　エックスなのか　なるほど　なかなかやりおるわい

やつが　エックスなのか・・・　なるほど　なかなかやりおるわい。

Ellipsis added, and some of the text formatting was changed.

かれの　のうりょくは　きけんですねいまのうちに　たおして　しまわなくては・・・

たしかに　かれの　のうりょくは　きけんですね。いまのうちに　たおして　しまわなくては・・・

エックスの　しょりはわしらの　ぶかにまかせるとするかの

こやつの　しょりは　わしらの　ぶかにまかせるとするかのう。

わたしたちの　もくてきのためにはあのレプリロイドのちからが　ひつようなのです。

X-Hunters Intervene

エックス！ さすがに　いちどは シグマさまをたおしただけのことは　ありますね

・・・エックスめ！・・・さすがに　いちどとはいえ　シグマさまをたおしただけのことは　ありますね。

・・・ あのものの さいごの パーツが ハンターきちにかくされていると メットールから つうしんが きましたわ

そうか！ ではさっそく あのものの パーツのかいしゅうに むかうとするかの

These two lines were removed from the final draft.

ケインはかせ！ これはいったい なにがおこったのですか

ケインはかせ！ なにか　およびですか？

カウンターハンターとなのる　さんたいの イレギュラーのしわざだ・・・

カウンターハンターとなのる　イレギュラーからつうしんが　はいったのじゃ。

From here the early draft goes off in a different direction...

エックス・・・ゼロの きおくかいろは ぶじか？

はい ここにありますイレギュラーたちは こんを ねらっているらしい

ふふふ・・・ついにみつけましたよ

！ だれだ！

エックスをわれわれと かけを しないかねあなたの そのパーツと わたしたちの かいはつしたパーツを あわせると ゼロはふっかつします

わしら カウンターハンターと あんたとのたたかいでしょうりした ものが このパーツ すべてをてにいれることができるのじゃわるい とりひきでは ないじゃろう？わしらは せんきょした ポイントでまつことにするが

・・・エックス！これはわなたいってはだめだ！

ゼロは おれの しんゆうです！ケインはかせ おれはいきます！

Light Capsule - Arm Parts

りょうてに　エネルギーをためてれんぞくで　こうげきすることができる　ダブルショットじゃ

りょうてに　エネルギーをためてれんぞくで　こうげきすることができる　ダブルチャージじゃ。

This is just a formatting and terminology change between versions. In the early draft, the fourth level X-Buster shot is referred to as "Double Shot", but in the final it is called "Double Charge".

Agile - Defeated

このわたしを　ここまでおいつめるとは・・・しんじられん！あなたを　あまくみていたようですまたあいましょう

このわたしを　ここまでおいつめるとは・・・しんじられん！あなたを　あまくみていたようですね。つぎに　あうときをたのしみにしていますよ・・・

All Stages Cleared - All Parts (Unused)

ダブルゼロ　ポイント　なんきょくてんだ！

ダブルゼロ　ポイント　ほっきょくてんだ！

The X-Hunter's base switched poles, probably because the stage select map scrolls up to get to the base, not down.

これで ゼロをよみがえらせることができるぞ だが

ゼロのしゅうふくには　もうすこしじかんが　かかる。それまでがんばってくれ。

すこし　じかんがかかりそうだもうすこし がんばってくれたのんだぞ　エックス

すこし　じかんがかかりそうだ。 もうしばらくがんばってくれ。  たのんだぞ　エックス。

Violen 2 - Defeated

ヤツが　オレよりもすぐれているとでもいうのか！このオレのパワーがつうじぬとはぐあああああっ！

キサマが　オレよりすぐれているとでもいうのか！このオレのパワーがつうじぬとはぐあああああっ！

Serges Tank - Defeated

ワシはしぬのか？

ワシはここで　ほろびるのか？

Sigma & Zero - All Parts (Unused)

おのれ　ゼロ！なぜきさまは　わたしのてきにまわる！

おのれ　ゼロ！なぜきさまは　わたしにキバを　むける！！

エックス　またせたなだが　あいさつはあとだいますべきことは

エックス　またせたな。だが　あいさつはあとだ！おれたちがいますべきことは

Sigma & Zero - Not All Parts (Unused)

ゼロ・・・このパーツをきみにかえすよ

ゼロ・・・

おれがわかるのか！ゼロ！

！　きおくが　もどったのかゼロ！

ゼロ！ しぬきか！

しぬきか！　ゼロ！！

Just a simple swap of sentences.

おれなら　だいじょうぶだはやくいけ・・・

おれなら　だいじょうぶだはやくいくんだ！

Sigma Fight (Unused)

どこまでも　わたしのじゃまをしたいというのかねエックス！

どこまでも　わたしのじゃまをしたいというのかね・・・エックス！

Sigma Virus

・・・だがわたしはなんどでもよみがえりあらたなちからをもちうることが　できる

・・・だがわたしはなんどでもよみがえりあらたなちからをえることが　できる。

しかし　ゼロはなぜ・・・やつは・・・　さいごの・・・ワイ・・・　リー・・・の・・・

しかし　ゼロはなぜ・・・やつは・・・　さいごの・・・ワイ・・　ナン・・・ズの・・・

The final game breaks up the phrase "Wily Numbers" to try to keep it somewhat mysterious, while the early draft just outright states Wily's name.
