Gunstar Super Heroes

Gunstar Super Heroes is a sequel/remake of the Genesis original.

Unused Music
Several unused music tracks exist in the ROM. The game was originally supposed to feature numerous references to classic Sega games, but unfortunately, they were axed very late in development. All of these songs were based off of their Genesis/Mega Drive versions.

Alone Fighter
One of two tracks from Galaxy Force II. Since there are two space segments, the Galaxy Force tracks were likely supposed to have been used there. This song appears first in the ROM.

Burning Point
From Super Thunder Blade. This probably would've played during the first portion of Moon 2, since it plays like Thunder Blade.

Final Take Off
From After Burner II. This is one of the tracks that was actually heard in a pre-release trailer, in the first section of Moon 1. Numerous noted references to "AFTER BURNER" further cement this.

Altered Beast
From...Altered Beast. Starts with the opening from "Rise From Your Grave". Likely would have been part of Black's Dice Maze along with a matching boss.

ESWAT Boss
From ESWAT: City Under Siege. May have been used during the boss rush before the final boss, as it seems to fit the mood there.

Wilderness
From Golden Axe. Unknown where it would play, since there don't seem to be any Golden Axe references.

Beyond The Galaxy
The second of the two Galaxy Force II tracks. This one appears to be early and unpolished: it has a false start, stopping after a few seconds, and loops after the first main section.

Unused Graphics

"Teddyman". (Colors are incorrect.)



Numerous unused attack frames for Golden Silver, which clearly show that the final boss was supposed to be able to use melee attacks against the player.



Kicking animation for what appears to be a male version of Red. (Colors are incorrect.)



Unused rolling sprites for Red. (Colors are incorrect.)



Early artwork for female Red. (Colors are incorrect.)



Early artwork for Blue, using a very different character design. (Colors are incorrect.)



Early artwork for Yellow, also using a very different character design, which appears to depict her piloting...something. (Colors are incorrect.)



Unused portraits of Yellow and Green.



Some unused tiles and names for areas of Black's Dice Maze.



An unused font, which includes a logo for something called "kein soft dec."



Unused tiles, likely debugging-related.

Regional Differences
Between the Japanese and American versions, most of the differences were merely aesthetic.
 * Many voice samples (including just about all of Red's) were changed.
 * A lot of the Engrish was cleared up, though at least one throwback to the prequel was lost in the fix.
 * One of the last bosses of Black's board had the save file delete threat removed.
 * Certain background details were erased or altered, including the electronic Japanese writing on one of Earth's buildings.

The European Gunstar Future Heroes had further changes, such as multiple languages (including Japanese, which still refers to the group as Gunstar Super Heroes) and changing Earth's menu symbol to that of a rotating "goddess" (Mother Earth?) similar to that seen decorated in the 3YE headquarters. To simplify the language select option, the level names were entirely removed.
