Key points

100% Steam Achievement completion in this collection is impossible without Sonic the Hedgehog, Sonic the Hedgehog 2, and Sonic 3 & Knuckles which were delisted on May 20th 2022 to be included in Sonic Origins.
Emulated versions of classic Sega Mega Drive/Genesis games.
Retail version is known as Sega Genesis Classic Collection: Gold Edition and was released in 2011
As of April 28, 2016 the collection now features Steam Workshop support.[3]
The Steam Workshop however has became flooded with illegally pirated ROMs (including games being sold through Steam or other platforms) and pornographic content disguised as mods with no substance due to lack of moderation of submitted content.[4]

General information

Steam Community Discussions


Source DRM Notes Keys OS
Original individual volume releases. Europe only. Missing Eternal Champions, Shadow Dancer and Pack 5.

Icon overlay.png
DRM-free after installation through Steam client (notes may include more details)
Complete pack.
Hub launcher requires Steam DRM. Simple launcher is DRM-free when launched directly from the executable (<path-to-game>\SEGAGenesisClassics.exe).
macOS (OS X)
Games are sold on Steam individually or in smaller bundles.
Some games are not available in Germany: see the DLC list.
Since the update of May 29, 2018, some regional roms can be played through the emulator: see the DLC list below.
The Steam version includes both the "Hub" launcher with the "Simple" launcher as a fallback. All non-Steam versions only includes the "Simple" launcher.

DLC and expansion packs

Essential improvements

Run in other emulators

For the Steam version, uncompressed ROMs of the purchased games can be found under <path-to-game>\uncompressed ROMs.
Most regional ROMs are unavailable in the uncompressed ROMs folder; instead, they need to be extract from the data folder.
Copy Steam ROMs to an external folder for use with other emulators[citation needed]
  1. Copy the contents of <path-to-game>\uncompressed ROMs and paste to another emulator's ROM folder of your choice.
  2. Rename *.68K and *.SGD file extensions to *.bin so that other emulators will correctly recognize and run them.
  3. Workshop mods are *.bin files inside folders found in steamapps\workshop\content\34270.
  4. External emulators can load these Workshop mods, copy the contents of 32470 to your chosen ROM folder, and rename the *.bin filenames as you see fit to prevent future confusion, then load them with your emulator.
Extract *.pak files with QuickBMS (non-Steam versions)[5]
  1. Download QuickBMS.
  2. Download the Sega Classics script (further down the page).
  3. Run QuickBMS and choose the Sega Classics script.
  4. Choose the installation folder containing the *.pak files.
  5. Choose the folder to save extracted ROMs to.
  6. QuickBMS will now extract the ROMs. Press Enter when done to exit QuickBMS.
  7. The ROMs are now extracted and named appropriately, ready for use with a different emulator (see Emulation:Sega Genesis)

Run mods in simple launcher

This program allows you to extract ROMs from SEGA Genesis Classics .pak files and to make your own for use with the emulator.
Use SEGA Genesis Classics ROM Packer[6]

Issues unresolved

Unable to disable controller

The input settings should contain a checkbox to disable a controller, but the checkbox is sometimes missing:

The inability to disable the controller affects Alien Storm. The second controller must be disabled to access one of the game modes.

Issues fixed

Run the game at screen refresh rate

2011 Gold Edition forces 60 Hz refresh rate even if your monitor supports higher than that.
Override refresh rate set by game[10]
  1. Download Chiri's resolution forcing tool.
  2. Extract d3d9.dll and d3dx.ini to the installation folder.
  3. Open d3dx.ini.
  4. Change refresh_rate=60 to desired hertz; e.g. refresh_rate=120.

Blank full-screen mode (Linux)

Playing games in full-screen mode in the Linux version of the SEGA Game Room does not work with AMD Mesa drivers.[11]
Run the Windows version with Proton

In the Compatibility tab of the game's Properties window in Steam, enable the "Force the use of a specific Steam Play compatibility tool" option and select Proton 6.3-8 or newer from the drop-down list.

Green faces with Sword of Vermilion

The game was designed for older TV CRT monitors. On computer monitors, faces of certain characters look green.[12]
Workaround: RetroArch CRT Render filter
  1. Follow Run in other emulators instructions listed above, retrieving sov.smd for use with RetroArch.
  2. Load shader preset crt-royale-ntsc-320px-svideo.glsp


  • This doesn't remove the green face, but rather blurs it to make it more like skin tone.
  • You can also experiment with the graphics filter parameters to get a less distracting look.

Game crashes on start

The game crashes on start. The game writes an error.log file showing the message "UnityPlayer.dll caused an Access Violation". This can be caused by a bug in the Unity framework conflicting with Citrix Workspace App. A workaround is available via uninstalling Citrix Workspace App and re-installing with some installation parameters that avoid this conflict.
  1. Uninstall Citrix Workspace App.
  2. If you still require the use of Citrix Workspace App then reinstall Citrix Workspace App but install from a command prompt, using the below command line:

CitrixWorkspaceApp.exe ADDLOCAL=ReceiverInside,ICA_Client,AM,SELFSERVICE,DesktopViewer,Flash,Vd3d,WebHelper,BrowserEngine"

    Attempting to select 3840x2160 from the Simple launcher's fullscreen resolution options and the emulator refuses to save settings. I've attempted to use aspect-ratio correction, disabled filter, windowed mode, and selected the Xbox One controller as the input device while fullscreen resolution is set to 3840x2160, but the Simple launcher always seem to reset settings every time if a 4K resolution is selected. Resolutions below 4K such as 2160x1440 however appear to work fine.)
