BizHawk vs PicoDrive

BizHawk is a free multi-system emulator for Windows and Linux, built around the EmuHawk interface. It is aimed at Tool-Assisted Speedrunners and combines playback with recording and debugging. The project lists systems including 3DO, Apple II, arcade machines, Atari, Commodore, Nintendo, Sega, and PlayStation consoles. EmuHawk provides 10 hotkey-operated save slots as well as unlimited named savestates, along with speed adjustment, frame stepping, and rewind. Users can record input as TAS movies and save screenshots, audio, and video. Debugging tools let users inspect, search, and edit memory across emulated hardware, while Lua or C#.NET can control the core and frontend programmatically. Keyboard, mouse, and gamepad hotkeys can be rebound, and an input mapper covers emulated gamepads and peripherals. The Linux build targets x86_64 and omits Mupen64Plus for N64. Current releases are unavailable on Android and iOS; macOS use is limited to older releases or technical workarounds.

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.
