What PicoDrive is

PicoDrive is a free emulator for Sega 8-bit and 16-bit systems, including the 32X. It runs games for Mega Drive/Genesis, Sega/Mega CD, 32X, Sega Pico, SG-1000, SC-3000, Master System/Mark III, and Game Gear. For compatible CD games, it supports enhanced cartridge audio in MSU, MD+/32X+, and Mode 1 formats loaded from CUE or CHD files. It can show Sega Pico Storyware pages and pad overlays from PNG files alongside the cartridge image. On systems with physical mouse support, a mouse can act as a Sega Mouse or Pico Pen. Keyboard support covers Sega Pico and SC-3000, including a virtual keyboard overlay; SC-3000 cassette emulation accepts WAV and bitstream tape files. The project documents generic Unix-like and libretro builds. Its release script creates packages or ZIP archives that users install manually. Windows and Linux are listed platforms, and self-hosted use is described. The README says most development activity happens in a fork and that the original repository is updated less often. For 32-bit ARM CD-game MP3 playback, Helix source files must be obtained separately.

Getting started

Open the PicoDrive project website on GitHub.
Choose a Windows or Linux package, or a ZIP archive produced by the release script.
