Sonic the Hedgehog Genesis

Sonic the Hedgehog Genisis is a GBA remake of Sonic the Hedgehog, originally released for the Sega Genesis. There are a few differences from the orignal game.

Differences

 * The screen ratio has been reduced to fit the GBA screan and keep everything the same size.
 * A new Anniversary mode has been added so you can do a spin dash which was introduced in Sonic the Hedgehog 2, or you could play the original mode with no spin dash.
 * The music and some sound effects were remade.
 * The game lags more than the original. Coupled with the small screen, this caused a lot of negative reviews.
 * The debug mode and level select mode has been removed but has an unlockable juke box room.
 * The game saves any zones you've been to so you can replay them or continue from them but does not save any Chaos Emeralds or your score.
 * If you quit the game without getting a game over, retry can be selected at the mode select screen so you can continue your game with your emeralds and score, and start on the act you left off.

Goal
The goal of the game is to get to the end of the act and flip the flag while collecting rings and stomping enemies and freeing little animals. At the end of every third act is a boss fight between Sonic and the evil Dr. Robotnik, after which you open a capsule containing little animals.

Zones
Sonic the Hedgehog Genisis consists of seven zones. Each zone consists of three acts. The zones are as follows:


 * Green Hill Zone
 * Marble Zone
 * Spring Yard Zone
 * Labyrinth Zone
 * Star Light Zone
 * Scrap Brain Zone
 * Final Zone

Special Zone
After collecting at least fifty rings and compleating the first or second act there will be a giant ring that if you jump through it takes you to a Special Zone with a chance to collect one of six Chaos Emeralds. The Special Zones on this are 2-D mazes that rotate costantly. The goal is to find the Chaos Emerald at the end without touching the goal orbs that take you out of it. You also have a chance to collect a lot of rings for 1-ups or to improve your score.
