As Sonic, you will go on an amazing adventure to get back the chaos emeralds and stop Dr. Robotnik
This game was originally released on the Sega Mega Drive/Genesis and has come back on the Playstation Network!
Note: The Use of Saving
This game allows you to be able to save at any time during the game. Simply Pause, then go to Save Game. This saves your exact position you left on the screen. This is considered the game's only cheat as you can use this to load up the previous save if you accidentally die or don't hit a target time you wanted. Use this to your advantage. For example, in the very difficult Scrap Brain Zone, it's very hard not to die. Proceed a little in the act, save, and then proceed more. You do this so that if you die you can load up the previous save to know what's coming. Warning: Make sure you are in a safe spot to save. If you trap yourself in a position where you will die, there is not much you can do.
Step one: Playthrough #1 (Getting everything not speed run related)
The goal for this playthrough is to play the game carefully. Your aiming for getting all the trophies here is not speed run related. For the very first level (Green Hill Zone Act 1) focus on getting the Centurion trophy. From this point you will also be trying to get every single chaos emerald (by ending an act with 50 rings) and beat the game without dying. See Chaos Master and Perfect Win.
KneeKnee has been kind enough to send a link to view all the acts. It's nice to get an idea of the acts, but they don't show every single detail such as enemies or certain objects. Here is the link: Sonic the Hedgehog Level Maps - Sonic Retro
Step two: Playthrough #2 (Getting all the speed related trophies)
After getting some experience with the game, now you should try to get all the speed related trophies. This include Fast Green, Fast Marble, and the Fast Win trophies. See Fast Win trophy for details about time management.
You may choose to do step one or step two in any order but the order above is recommended.
