This page details one or more prototype versions of Sonic 3D Blast (Sega Saturn).

This article has just been started and needs the article basics added. Help us out and add them.

Released by drx as part of the February 23, 2008 proto dump, this was a semi-early build of Sonic 3D Blast on the Sega Saturn, dated October 8th 1996 (Exactly one month before its final American build date).

General Differences#

• Pressing Start skips levels. Sometimes this causes the game to lock up.
• Pressing A does a Spin Dash, while B and C are the jump buttons. In the final game, B does a Spin Dash, while A and C are the jump buttons.
• No bosses are present.
• Tails and Knuckles do appear in their intended positions but they won't take Sonic to their Special Stages.
• Diamond Dust Act 2, as well as both main acts of Volcano Valley, are absent.
• The only sound in this build is the sound effect of Sonic losing his rings, and it only plays on the title screen.
• Though the main menu has three buttons, they all sport the "Start" option.
• Later levels after Rusty Ruin don't have the necessary amount of badniks required to progress after a gate ring, and are impassable without skipping.

Visual Differences#

• Several Zones either have unfinished art, or borrow art straight from the Genesis version.

Tech Demo	Genesis	Final

• The title screen uses a higher quality version of the one in the Genesis version, with slight differences.

Tech Demo	Genesis 825 Proto	Final

• The menu background uses a higher quality version of the one in the Genesis version's 825 prototype. Curiously, Sonic's nose and hands are noticeably different compared to the Genesis version. They may have been remodeled and re-rendered, or simply touched up by hand, similarly to how Sonic's face was updated for the final Genesis version.

Tech Demo	Final

• The menu buttons use a more watery texture compared to the final game. It only accounts for the start button, so all three buttons look identical.
