    Introducing Amy Rose, Metal Sonic, and the Time Stones this is the first and only Sonic game to come out for Sega CD, with new characters, 3 endings, and anime entrances and closings this is considered by Sonic fans as one of the best Sonic games of all time! It came out in November of 1993, along with Sonic Spinball and was just rereleased for the PC in 1995, and the features are the same, the codes, the characters, everything. The only difference is that this time around they got Amy Rose's name right in the instruction booklet. This game presents time travel; Sonic can go into the past, present, and future realities of each zone! The future depends on whether you trash Robotnik's roboticizer in the past of each act; if you do, the future will be a good future where the animals are allowed to run free. If not, it will be a bad future where Robotnik is allowed to run amok. If you get the Roboticizers in the past of every act, you will see the good ending of the game. Otherwise, you'll see the bad ending...This game consists of the Palmtree Panic Zone, Collision Chaos Zone, Tidal Tempest Zone, Quartz Quadrant Zone, Wacky Workbench Zone, Stardust Speedway Zone - possibly the most famous Sonic Zone and the race with Metal Sonic - and the final confrontation with Robotnik, The Metallic Madness Zone!


    Dr. Robotnik's latest scheme involves the mysterious Little Planet, which appears on the last month of every year over Never Lake. The Little Planet houses the seven Time Stones, with which the holder obtains the ability to travel through time and space. With the control of time, nothing could stop the Eggman! Not to freak, because Sonic the Hedgehog is on the case! Unfortunately, Robotnik has decided to unleash Metal Sonic to keep the hedgehog hero at bay; and kidnap Amy Rose to further complicate the problem. Infact, Robotnik's already made use of the Little Planet's lack of any boundaries on time, and has placed robot machines in the past so he controls the future. Now Sonic's got to stop Robotnik, destroy the robot machines, collect the seven Time Stones, save Amy Rose, and deal with Metal Sonic on a tiny planet where time has no meaning. A hedgehog's work is never done....

    Code Versions
    Even though there are two versions of the game, one for Sega CD, one for PC, most of the codes match each other so I will only put one version of the code unless the other is needed. In the Sega CD codes, buttons A, B, or C can be substituted with the space bar for the PC version.

    The Master Code
    From the title screen, press Down, Down, Down, Left, Right, A (or Space) to call up a Sound Test menu. Special things will happen if you select the following sound combinations and press Start.

    Sounds                Effect
    FM40, PCM12, DA11     Construction/ Debugging Mode
    FM07, PCM07, DA07     Play All The Special Stages
    FM42, PCM03, DA01     Displays artwork
    FM46, PCM12, DA25     More artwork
    FM42, PCM04, DA21     Sonic Hercules
    FM44, PCM11, DA09     Revenge of the Mutant Artwork

    Level Select
    At the title screen, press Up, Down, Down, Left, Right, B (or Space).

    Note: This code only lets you play one level. You will be sent back to the title screen upon completion or if you time warp.

    Beat the Clock
    First, finish the game successfully. Now play Time Attack and beat the following times for some special options.

    If you beat this time you can play the bonus stages in Time Attack. To access these stages, press Left in the Time Attack screen.

    Beating this time adds a new item to the main menu. To the left of RAM Data there will be an entry titled D.A. Garden. It's a picture of the little planet. With the controller you can rotate the planet (with B), zoom in and out (with C), and listen to all the music in the game (with A). It allows you to listen to the regular music, a good mix, and a bad mix, for each level.

    Finally, if you can beat this time another menu item appears. To the left of D.A. Garden you'll find Visual Mode. This option allows you to watch the introduction, the endings, and a pencil test of Sonic running around. It also has a cool picture of Sonic in the background.

    Tip: To beat these times easily, enable Debug Mode as described under Cheat Codes and Sound Test. This will disable the clock so you'll always finish in 0 seconds!

    Designer's High Scores
    To see the high scores of the game designers, press Right, Right, Up, Up, Down, C.

    I'm Outa Here!!!!
    If you let Sonic sit for three minutes without doing anything, he'll grow bored, say "I'm outa here!" and race off the screen, thus ending the game.

    Quick Death
    For the masochistic hedgehog in you, here's a way to kill yourself quickly. While playing, pause the game and press A, B, or C. This can be useful if you find yourself trapped.

    Weather Control
    To change the clouds on the title screen, hold A while pressing Up, Down, Down, Down, Down, Up.

    The Secret Special Stage!!!
    Enter the Sound Test screen, and enter 7's in all the boxes. When you play that sound a secret stage will appear.
