Genesis Plus GX review
A broad Sega emulator with save states, hardware emulation, cheats, filters, and netplay.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Genesis Plus GX is an open-source emulator focused on Sega's 8-bit and 16-bit systems. It supports Genesis/Mega Drive, Sega/Mega CD, Master System, Game Gear, SG-1000, and preliminary Sega PICO emulation. The project is suited to players and preservation-focused users who want one emulator covering several Sega console families, with support for multiple ROM and CD-image formats. Official ports include standalone GameCube and Wii versions, while the core is also used through RetroArch, BizHawk, and OpenEmu. Windows is the listed platform in the product profile.
Its feature set goes beyond basic game launching. Genesis Plus GX provides save states and automatic state-file saving, along with peripheral and cartridge hardware emulation. It also includes Game Genie and Action Replay hardware emulation, RetroArch cheat support, and NTSC and other display filters. These features make it a focused choice for users who want control over saves, visual output, cheats, and system-specific hardware behavior across a broad Sega-family scope.
The main boundaries are equally clear. Sega PICO support is preliminary, and netplay is available through the libretro core rather than as a standalone feature described separately. The project is free for non-commercial use under its stated license, with no paid plan structure. Choose Genesis Plus GX for dedicated Sega coverage, open-source availability, hardware emulation, and integration with established emulator frontends. Users seeking a narrower Genesis-only tool, or a product centered on independently documented netplay or mature PICO support, should consider an alternative.
