Sonic 3D Blast is an isometric Sonic game where you have to rescue Flickies (the concept is based on the classic Sega title Flicky), and is considered to be mediocre by many. Somewhat-improved versions were later released for the Saturn and Windows.

Level Select

As the wavy text indicates, a veritable roller-coaster of mediocrity.

At the title screen, press B, A, Right, A, C, Up, Down, A. You'll hear a twinkly sound and be taken to the main menu. Set your desired options, choose "START", and you'll be presented with the Level Select.

(This is probably much better for the long-term health of your console and cart than the next method.)

Cleverly-Disguised Crash Handler

"Smash TV" also hides the fact you just broke the game.

A somewhat unique exception handler where, unlike (for example) the Sonic 1 crash-and-print-text-on-the-screen, the game congratulates you and loads up the Level Select. Obviously, this method of crashing is much more appealing to the player than a complete lockup, and may have prevented a number of angry tech support calls. It could also have been designed as a way to limit the "damage" of a crash, as a player whose game crashed while pretty far into the game would not need to start over from the beginning.

There are numerous methods for activating this screen: loading a bad savestate, using a bad Game Genie or Pro Action Replay code, pulling the cart out and putting it back in, having dirty contacts on the cart/console, hitting an obscure program bug, etc.

Truncated Music

The invincibility theme only plays for about 18 seconds in-game, but there's a bit more to it that can only be heard in the sound test.


Unused Areas

Green Grove Zone Act 1

After passing the first loop of Act 1, there is a large empty area blocked off by a wall. In the E3 prototype, this area is properly accessible; apparently, only the collision was removed. Lower down, there is another area that does not appear in the E3 prototype.

Diamond Dust Zone Act 2

An alternate route exists blocked off towards the beginning of the act, just after the first spring.

Spring Stadium Zone Act 2

There's a blank collision area set at a very low level near the coiled tube.
