Cycle-accurate Mega Drive emulator (BlastEm). Extremely precise for testing and development, less fast than Genesis Plus GX. It covers the following systems: Genesis, MegaCD, Sega 32X.

1. Installation

  1. Get the latest version from the project's official website.
  2. Extract the archive into a dedicated folder.
  3. Launch it once: it creates its configuration and subfolders.

2. Accepted formats

.md .bin .gen

3. Good to know

  • The MegaCD/Sega CD needs a BIOS file (e.g. bios_CD_U.bin); the Genesis and 32X do not require one.
  • Set up your controller the first time you launch it — that saves the most time.
  • Save states let you resume exactly where you left off, in addition to the game's own saves.
  • A setting that works for one machine won't necessarily work for others: adjust case by case.

4. Not working?

  • The game doesn't show up → check that its extension is one of the formats listed above.
  • Crash on launch → relaunch from a folder the emulator has write permission to.
