Rockman X4 (ロックマンX4) is a manga by Iwamoto Yoshihiro based on the game of same name. It was originally serialized in Comic BomBom from September 1997 to August 1998 in 12 chapters, and later compiled in two volumes in 1998. Mega Man Xtreme is an action-platform game that features the same gameplay as the Mega Man X games on non-handheld game consoles. As the titular protagonist, the player is tasked with completing a series of selectable, side-scrolling stages in any order desired.

• This is the Japanese Windows version of Mega Man X4 (known as Rockman X4 in Japan). It's compatible with Windows 95 and up, and runs well in NT versions as well if DirectX 6 or better is installed. Runs in non-Japanese language versions of Windows as well.
• Mega Man X4, known as Rockman X4 (ロックマンX4 Rokkuman Ekkusu Fō) in Japan, and often shortened to MMX4, or just X4 by fans, is the fourth game from the Mega Man X series.

Mega Man X4 marks X's entry to the PlayStation and Saturn as the Maverick Hunter has to team up with his buddy Zero and fight off an entire Reploid army that decides to go rogue because everyone is bad at basic communication. The game has many similarities to its sibling Mega Man 8 and marks the cut-off point where many fans think the series jumped the shark. Plus the infamous 'WHAT AM I FIGHTING FOR!'

Unused Enemies

Graphics from the Mega Man X5 enemy Rollin' Gear are present in the data from the second section of Storm Owl's stage.

Unused Sprites

Unused frames of the character Double. While the first sprite to the left is entirely unused, the two on the right can be briefly seen just as a stage is being selected. The running sprite is shown while choosing one of the regular eight stages, while the one on the right shows up while the second Final Weapon stage is being selected.

Used in a demo version of the game. A placeholder graphic for boss portraits, particularly for unavailable stages.

Used in a demo version of the game. A placeholder graphic for boss portraits, specifically for selectable stages that have unimplemented bosses.

Unused throughout all known versions of the game, and untouched in the international versions. Palette data for these two images still exists, however.

Unused Gameplay Demo

Located on the NTSC disc is a file called 'PLDEMO.ARC' containing data for an unused demo. This file is not present on the Japanese release. The demo starts X at the final boss, which for spoiler reasons is probably why it was cut (that and the atrocious playing).

This footage was captured by copying the data from 'PLDEMO.ARC' over one of the four demo files that are used.

Regional Differences

Title Screen

The images of X and Zero from the player select screen slide across the title screen's opening animation. This was simplified in the International builds.

Intro Music

The Japanese opening song, Yukie Nakama's 'Makenai Ai ga Kitto Aru', was replaced with a different track for the international releases.

Credits Music

The Japanese ending song, Yukie Nakama's 'One More Chance', was replaced with a different track for the international releases.

Name Changes

As with the first three games, the eight Mavericks go under new names overseas, save for Split Mushroom.

Voices

Some voices, such as the pre-battle voices from the eight selectable bosses, were disabled in the international releases. While these bosses do still retain their voices during battle, Cyber Peacock is the only one who's been muted entirely.

• Despite being disabled, all Japanese pre-battle voices of Maverick bosses are still present in the game's voice data set. The English PC version removed all Japanese voices and battle cries properly but only replaced them with dummy data files, and all of them are interchangeable with voice files used in the Japanese PC version.

Revisional Differences

The Mega Man X Legacy Collection version of the game has a few differences from the original PS1 release.

General Salute

The scene in the intro where the General does a salute was removed, possibly due to it resembling a Nazi salute.

Flashing Lights

Cutscenes where the screen flashes rapidly was changed to have the screen be dim.

Save Feature

The amount of save slots has been increased from three to six.
