Sonic Adventure (LCD game)

Sonic Adventure is a handheld LCD game released by Tiger Electronics in 2000 as a tie-in to the Sega Dreamcast game also called Sonic Adventure. The game is known for it's rarity and is a sought after item for Sonic collectors.

Description
The game is a part of Tiger's "Arcade Games" series. Each had a tabletop arcade style design, optional screw-on joystick, 4 buttons "A", "B", "C", and "D". It also came with a "Reset", "On/Off", "Pause/Start" and "Sound" button. Unlike most Tiger games, this model has a pixel based LCD display similar to their previous 99x series of games but with a lower resolution. The screen casing is blue with decals featuring Sonic Adventure artwork of Doctor Eggman and Sonic the Hedgehog. The controller casing is black with yellow and red buttons. The 4 double A batteries go under the case.

Gameplay
The game features 7 levels with the same names as their the Dreamcast counterpart, albeit shorter and more linear. Each level ends in a boss fight or a Capsule followed by a boss fight. All bosses can be defeated by homing attacking them 3 times. The game progresses as follows:


 * Chaos 0
 * Stage 1: Emerald Coast
 * Egg Hornet
 * Stage 2: Windy Valley
 * Knuckles the Echidna
 * Stage 3: Ice Cap
 * Chaos 4
 * Stage 4: Speed Highway
 * E-102 Gamma
 * Stage 5: Red Mountain
 * Chaos 6. You need to pick up an item and throw it a Chaos before you can homing attack him.
 * Stage 6: Sky Deck
 * Cannon. Launch rockets at it to defeat it.
 * Stage 7: Final Egg
 * Egg Viper. This boss has three stages.

As can be expected from a handheld version, many events from the Dreamcast version of the game are missing, and many are 100% scripted such as touching springs. The game also has no music and a limited number of sound effects.

Codes
The game also features several codes that can be entered on the name screen. These are given out after finishing the game or boss rush mode, but they're not hard to guess because of their simplicity and the name input only accepts 4 characters. The codes are:


 * "supe" for invincibility
 * "rings" for full rings
 * "life" to start with extra lives
 * "boss" for a boss rush mode

Trivia

 * One stock image of Sonic shows him having flesh colored eyelids, which he doesn't have in the original image.
