macOS (OS X)
All digital versions require Steam DRM; DRM-free versions are no longer sold.
Games are sold on Steam individually or in smaller bundles.
The Steam version includes both the "Hub" launcher with the "Simple" launcher as a fallback. All non-Steam versions only includes the "Simple" launcher.
The Sega Mega Drive and Genesis Classics package on Steam also includes Sonic CD, however Sonic CD runs natively (without emulation) and does not use the launcher.

Downloadable content (DLC) and expansions

Essential improvements[edit]

Run in other emulators[edit]

For the Steam version, uncompressed ROMs of the purchased games can be found under <path-to-game>\uncompressed ROMs.
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)[citation needed]
  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)
