ClownMDemu is a highly accurate and minimalist Sega Mega Drive (Genesis) emulator core for RetroArch, based on the ClownMDemu project by Clownacy. It focuses on delivering cycle-accurate emulation of the Mega Drive’s core components, including the 68K CPU, Z80 co-processor, and VDP, with exceptional timing precision.
This emulator is written entirely in C with no dependencies, resulting in a clean and lightweight implementation that’s ideal for developers, preservationists, and purists who seek faithful reproduction of original hardware behavior.
Key Features:
- Cycle-accurate emulation of the Sega Mega Drive (NTSC).
- Low-level implementation of CPU, VDP, and audio hardware.
- No external dependencies – completely standalone.
- Focus on accuracy over compatibility – may not run every game, but emulates supported games with high fidelity.
- RetroArch core version maintained as part of the libretro ecosystem.
This is not a general-purpose emulator for casual use, but rather a project aimed at accuracy and educational value. Perfect for those interested in emulator development, reverse engineering, or testing Mega Drive hardware behavior with pixel-perfect precision.
