Mega Man Zero Collection

Mega Man Zero Collection is, as the title suggests, a collection of the four GBA Zero games. It also fully opened Capcom's floodgate of re-releasing past game titles.

Anti-Piracy#

This game utilizes the DS Protect anti-piracy library to ensure that it is not being run off a flashcart or emulator. If any of the DS Protect checks fail, the game scrambles the tile graphics.

Unused Music#

While the multiplayer minigames of Zero 2 are disabled in Collection, the music tracks used in said mode are still present in the ROM.

BGM_ZC2_184 Fanfare meant to be played in multiplayer mode stages. The percussion is very similar to the Get a Weapon music from Mega Man 2.

BGM_ZC2_185 Music track "Red Time" which is meant to be played in the multiplayer mode preparation screen.

Regional Differences#

Title Screen#

Japan	International

While the European version shares the main menu title screen from the US version, the Europe-specific variants of the individual game title screens are used for Zero 2, 3, and 4.

Mega Man Zero Title Theme#

Though regional differences were dealt identically to their original releases, both variations of Mega Man Zero's title theme are in the ROM of the international releases.

BGM_ZC1_118 is the variation with the "Rockman Z!" voice clip which is only used in the Japanese version, while BGM_ZC1_118a is the international variation without said voice clip.
