Introduction:
This is not a port. Forget everything you know about ports of classic games. This is a completely new game and standard, rebuild with a new game engine specifically designed for modern consoles and systems, designed to run flawlessly with HD TV’s updated with all the delights the modern age can bring. Sonic CD has raised the bar for what classic titles should be.
Sonic CD is still the same classic title you may remember from the days of the Mega CD, but treat this as a new game made specifically for the modern day. The game has 12 trophies and several other secret extras. So what are you waiting for! Go save the planet before it’s too late!

Missable Trophies
Almost every trophy in the game is missable in that the moment you beat a zone, you have to restart the whole game until you reach that specific zone again in order to get that trophy. For trophies like Saviour of the Planet you will have to get every robot teleporter on every zone again until you get to the one you missed. Ensure you use a guide or a visual aid when mentioned in the trophy.
Why 3 playthroughs?
According to users over at The Sonic Stadium forums, one trophy cancels the other out, Saviour of the Planet cannot be unlocked if you get all the Time Stones (Treasure Hunter) and vice versa.
This has now been confirmed by Flames.
The third playthrough is the time travel mode, which forces the player to replay every stage and boss fight, hence it being an entire playthrough.
Ah but I did it in 2 playthroughs!
Yes you did, well done for taking the harder method. You can get all time stones and destroy all the robot generators in one playthrough, then you'll just be left with the time attack trophy.
You can destroy the generators and holograms then start collecting time stones so that the last one you get is on Metallic Madness Act 2. However, doing this is much harder than simply dedicating one playthrough to the time stones, not to mention, finding 50 rings in the later stages of the game and keeping them is a very hard task.
Unless you want a much harder challenge, you are much better off just doing one run dedicated to the time stones, then a second for the robot generators/holograms. For new players to the game, attempting to do only two runs is not advisable due to the restrictions you place on yourself for the Special Stages.
Walkthrough:
In this road map and guide, I will be referencing a website known as Zone: 0 a lot. Why? Because it’s by far the best guide anywhere for Sonic CD, it contains full colour maps, detailed walkthroughs and advice for beating the game. Whilst it was written for the Mega CD/Sonic Gems collection version of the game, its advice still applies and the information there will help you get 100% on this game. Please use it when directed in this guide as the stage maps will become vital for specific trophies.
Step 1: Time Stone Run
Use this playthrough to focus on getting 50 rings by the time you reach the end of zones 1 & 2 in each act, when you enter the special stage concentrate on beating it (see guide for more information). Chances are you will unlock most trophies during this initial run by accident, no need to go out of your way to go for too many missable trophies as you’ll be doing a lot of looking for your second run (Good Future Run).
For now, concentrate on simply beating Acts 1 and 2 with 50 rings and beating every special stage. Remember to quit the game if you reach the end without 50 rings and reload, or quit the special stage if you think you’re about to fail it. There are more chances to get into a special stage then there are special stages so you have more than enough opportunities to get all Time Stones.
By doing this you should unlock Treasure Hunter all story mode trophies and chances are several other missable trophies by accident.
Step 2: Good Future Run & Cleanup
First of all, use the Sonic CD guide at Zone: 0 for maps on each zone, this will give you the exact location of all robot teleporters, holograms, time travel posts and even hidden objects/paths for other trophies. It will also allow you to plan your route both back in time and to the target objects.
During this run, you are going out of your way to look for objects as opposed to carefully beating each zone with 50 rings intact. You should also use this as your clean up run too, try getting all missable trophies such as King of the Rings, Take the High Road & Heavy Metal. Remember, this pretty much a collectables type of run, taking time or finishing with a lot of rings doesn’t really matter so treat this as you would a cleanup run.
Step 3: Time Attack
Time Attack is a separate mode which is a lot easier than you may think, you should be very familiar with the game and it’s stages, most of the time it’s just a case of heading to the lowest path and holding up + jump in order to do the charged speed dash move.
See the trophy guide for more information as to how to get this one.
Step 4: Final Clean Up
In the unlikely event you are missing a trophy, now is the time to go back for another playthrough and get it. Chances are the only you are missing is King of the Rings and maybe statue saviour. However, if you treated your ‘good future’ run as a full collectables run, you should have 100%.
