Instead of ClownMDEmu
ClownMDEmu alternatives
ClownMDEmu focuses on Sega Mega Drive and Genesis emulation through a portable library. It offers a browser version, a standalone desktop frontend with debugging menus, and a libretro core for compatible hosts. Its relocatable save-state structure supports quick state handling and multiple emulator instances, while separate FM and PSG audio outputs and scanline video output fit software integration. The project targets Linux, macOS, Windows, web, and self-hosted use, and remains free under AGPLv3 or later.

You may prefer an alternative when Genesis alone is too narrow, when you need mobile support, or when you want a ready-made multi-system interface. ClownMDEmu’s maker describes a balance between correctness and performance rather than an accuracy-first design, and some Mega Drive features remain incomplete, including parts of 68k exceptions, reset handling, and VDP rendering. Building the core requires CMake and initialized Git submodules. Compare system coverage, debugging, controller support, netplay, browser embedding, installation style, and licensing before switching.
