Proto:Sonic 3D Blast (Genesis)/73 Prototype

Prototype 73 of Sonic 3D Blast, dated July 3, 1996, was released by drx during the February 23, 2008 proto release. It is the earliest dated prototype of Sonic 3D released so far.

General Differences

 * The Sega logo has the old "Sega" sound, and shatters at the end (like when you get a Game Over) instead of the letters zooming off the screen.
 * No intro movie is played (before starting a game, and after starting the game).
 * No level select is available.
 * No game demos play.
 * Platforms move back and forth with no pause
 * There are no title cards for each level.
 * Special stages are absent in this build, as are Knuckles and Tails.
 * Pressing A when the game is paused will skip to the next level.
 * The level complete screen is very basic, with no final score tally.
 * Blue Flickies run in circles, while purple Flickies mix the worse of the final green and red ones (move randomly and jump).
 * The invincibility, Speed Shoes, and Fire Shield powerups are all absent. Not even their art is present.
 * The player has to press C to make Sonic jump from the Goal Ring if the player collects less than five Flickies.
 * All levels use the Green Grove Act 1 music, while all bosses use the Final Fight music.

Aesthetic Differences

 * No dust appears while doing the Spin Dash.
 * When pausing the game, the "Pause" text will not appear.
 * The title screen is similar to several other prototypes released by drx and the Saturn version. The "Press Start" text does not appear:


 * Some of the monitors have their art incorrectly applied:


 * There is a bug which makes the Gold Shield a strange green/red color on some stages. They otherwise act normally.

Green Grove Zone

 * There is a Blue Shield close to the cannon in Act 1, instead of a Gold Shield.
 * There is a spiked ball near the first giant ring, which also isn't in the final.
 * No water splashing effects
 * The floor tiles are brighter:


 * Near the cannon, there is a shield on a hill. In the final, it's in a slight dip.
 * There are no rings in Act 3, although ten rings are already given at the beginning of the Act.

Gene Gadget Zone

 * The second zone of this prototype (sixth in the final), which does not yet have a boss.

Rusty Ruin Zone

 * The third zone of this prototype (second in the final), the first two Acts are flipped from how they are in the final.
 * Ballerina spinning thing doesn't make you invulnerable against enemies.
 * Slight changes to the Act layouts.
 * After beating the boss, you're sent to a screen with the text "To Be Continued". When the music ends, the game returns to the Sega intro.
