In their own words
Genesis Plus GX
Genesis Plus GX is a free, open-source emulator for Sega's 8-bit and 16-bit systems, including SG-1000, Mark-III, Master System, Game Gear, Genesis/Mega Drive, and Sega/Mega CD. It supports backward-compatibility modes and describes its CPU, video, and sound emulation as highly accurate, with cycle-accurate CPU and sound synchronization. The emulator reads raw and interleaved ROMs, as well as CUE+BIN, ISO+WAV, and ISO+OGG CD images. Emulated peripherals include 2-, 3-, and 6-button pads, multitaps, the Sega Mouse, and light guns; supported cartridge hardware includes SVP DSP, EEPROMs, Game Genie, Action Replay, and Lock-On. Standalone builds are available for GameCube and Wii, and the project lists access through frontends such as RetroArch, BizHawk, and OpenEmu. It describes compatibility with released software for its supported systems, while noting that it cannot test every game from start to finish. Some Master System games depend on particular hardware or VDP modes. The multi-platform core source is under a non-commercial license.
MEKA
MEKA is a free multi-machine emulator for Sega 8-bit systems and ColecoVision. It supports the SG-1000, SC-3000, SF-7000, Mark III, Master System, Game Gear, ColecoVision and Othello Multivision, along with a wide range of peripherals and unusual games. The project includes a debugger and tools for debugging and hacking, aimed at programmers and people working with Sega 8-bit systems. It also provides a game database and compatibility list, which the site describes as receiving fixes and changes. MEKA is free software under a BSD-like license, and its source and data may be browsed and reused without restrictions. The download page lists a Windows x86 build and directs GNU/Linux and macOS users to build from source. That page describes MEKA 0.80 as in development, while the GitHub releases page lists Meka 2025-08-17 as the latest release. Initiated in 1998, the project is maintained by Omar Cornut, known as Bock. The project says it has limited use for the average player.
