"Genecyst is a DOS based emulator for the Sega Genesis. The 68K, Z80, DAC, digital FM emulation and graphics rendering were written from *scratch* in assembly. The rest is in C++. It is freeware and it is not to be distributed with game ROMs and it is not to be modified or sold."

What is emulated:

  • 68000 CPU @ 8Mhz
    Sonic 3D Blast
    Sonic 3D Blast
  • Z80 secondary CPU @ 4Mhz
  • DAC output
  • YM2612 FM synthesis
  • TI76489 PSG
  • VDP
  • DMA
  • ScrollA/ScrollB/Sprites/Window
  • Some raster effects
  • H/V interrupts
  • Dual 4-button/7-button joypad emulation
  • US/Japan/Europe variants
Other neat features:
  • Multiple save states and battery backed ram
  • Joystick support
  • VESA support
  • Save .pcx snapshots
    Mega Man: The Wily Wars
    Mega Man: The Wily Wars
  • Game genie codes
  • Rom checksum fixer
  • Wave output logging
What it lacks:
  • Digital FM emulation needs much work
  • Stereo FM (probably not worth it)
  • Graphic equalizer
  • 68000 emulation is still buggy
  • Z80 emulation still buggy
  • H-ints aren't emulated correctly I dont think
  • Shadow/highlighting effects
  • Interlaced modes
  • Netplay
  • Many games do not work correctly (or at all).
  • Dont bother me if a ROM doesn't work.
