Loaded MicroSD Card for TerraOnion MegaSD – Complete Genesis / Mega Drive / Master System / 32X / Sega CD / Mega CD

Preloaded SD card for the TerraOnion MegaSD. Organized into folders and ready to plug and play!
(Looking for a card for the Mega EverDrive? We have them!)

Samsung or SanDisk cards based on available stock. We use no cheap unbranded Chinesium memory cards.

The 32GB option includes just the complete US Collection for Sega Genesis, Master System, and 32X, along with EU and JP disks, and over 450 Homebrew/hack Genesis cartridge ROMS. [View 32GB directory list]
The 200GB option also includes the complete US collection for the Sega CD, with additional international releases, tools, and hacks!  [View 200GB directory list]

Both the 32GB and 200GB collections are now updated to include a collection of MSU-MD and MD+ audio patched games!

  • Complete NA Sega Genesis collection as per this list.
  • Complete NA Master System collection as per this list.
  • Complete NA 32X collection as per this list.
  • Complete NA SegaCD collection as per this list.
  • SegaCD NA collection has been tested by hand to make sure each disk loads at least to the menu.

In addition to the sorted ROMs, I have also included the full GoodGen v3.21 set for Genesis/MegaDrive; mostly duplicates, but the full set includes every known release and variant cartridge organized in folders by game name.

32X required for 32X games. 32X-CD games included for completion and for use with other emulators, but these games are not yet supported due to hardware limitations. TerraOnion does not guarantee compatibility with every title; see the official website for support on your MegaSD.

Complete Sets include some duplicates as multiple versions of some cartridges were printed with slight variants, bug fixes, or sometimes censorship.

Note to Parents: Hacked ROMS are fan-made and may contain offensive or sexual content. If giving this set to younger children you may want to delete this folder entirely.

Seller neither holds nor implies any rights to the disc images on this collection, made of files freely available online, and intended for backup purposes only. Buyers acknowledge that they are paying for the physical media and my time in providing this collection only.
