PicoDrive is a freeware, open-source emulator for Sega 8-bit and 16-bit consoles through the 32X. It runs Mega Drive/Genesis, Sega/Mega CD, 32X, Sega Pico, SG-1000, SC-3000, Master System/Mark III, and Game Gear games, with save states. The emulator supports enhanced CD audio for compatible cartridge games in MSU, MD+/32X+ and Mode 1 formats loaded from CUE or CHD files. Sega Pico Storyware pages and pad overlays can be displayed from PNG files beside a cartridge image. Physical mice can emulate a Sega Mouse or Pico Pen, and keyboard support covers Sega Pico and SC-3000 devices, including a virtual overlay. SC-3000 cassette emulation accepts WAV and bitstream files and advances tapes when accessed. The project documents generic Unix-like and libretro builds. Release packages or ZIP archives are installed manually. Windows, Linux, and self-hosted use are listed. The PicoDrive plan costs nothing.
