Mega Man Zero
|Mega Man Zero|
Mega Man Zero is the first game in the Zero series. Decades after the X series, Zero is reawakened to a different world.
The sign for basement floor 2 was replaced with a blank blue rectangle. The other signs were removed entirely.
Various other messages overwritten with エラー in the English version; text dump comparison (possibly incomplete) here
This text translates to "We can't use the Trans Room to go to the city while the door is still locked... but we haven't managed to break the password yet."
This seems to be from a mission that they scrapped before, or possibly replaced with something else. By the context of the message, it seems that you were to need a pass key or something in order to access Neo Arcadia, rather than Ciel finding it out.
Another unused and untranslated bit of text from Ciel can be found right before the aforementioned block in the game's data. It is currently unknown if this can also still be triggered in-game.
|ゼロ 聞こえる? ゼロ
|Zero, can you hear me? Zero|
return to base IMMEDIATELY!
Another unused block of text said by Ciel can be found in the Japanese version, around the text used after finishing the Disposal Center mission. The text has been replaced by the word エラー (Error) in the English version. This event can still be triggered in the game, including enabling of the Escape Unit, if you manage to finish but fail the Disposal Center mission (ex. via memory editing), which is not possible under normal circumstances.
You don't have to exert yourself so much.
I was supposed to be invincible. But it's too late. You're still going to perish!
This was meant to be Maha Ganeshariff's death line, but in the final game he dies quietly.
The bank of text that contains mission and location names, Cyber Elf names and descriptions, etc., also contains a list of codenames for Zero, as used on the mission result screen. This list contains one unused entry that was left in Japanese, even in the English version, which reads ジャンキー (Junkie).
Title Screen Graphic
This image is loaded into the VRAM during the title screen and is used for the moving bars that seem to change color, move and merge into a single red bar which becomes the Z of the title logo. Starting from the top of this image, one horizontal line of pixels is stretched across the screen on a background layer and the source line moves down this image giving the illusion of motion and changing color. This effect can be seen here. This complete graphic can be seen in Visual Boy Advance's map viewer.
Europe didn't get a (relatively lame) title screen redesign by the point of first Mega Man Zero game.
The "Rockman Z!" voice clip was removed from all non-Japanese versions of the title track.
The walls in the Disposal Center also contain "robot blood" in the Japanese version.
Despite these changes, bosses are still cut in half when defeated with bladed weapons--although the large spurt was removed, no attempt was made to hide the "blood" visible on their sprites when this happens.
