Mega-Pi review
A focused, free Sega CD emulator for Raspberry Pi builds, with strong disc-image and audio support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Mega-Pi is a bare-metal Sega Mega Drive/Genesis and Sega CD/Mega CD emulator designed specifically for Raspberry Pi. It suits users building a dedicated Sega CD setup around an SD card, USB controller, and television or display. The feature set covers core console emulation alongside disc-based Sega CD support, with an on-screen ROM browser and favorites for organizing available games. Its focused hardware target makes it a specialized option rather than a general emulator for desktop or mobile platforms.
The published project workflow is more involved than installing a typical desktop application. Users compile the project, then boot it from a FAT32 SD card containing the emulator files, BIOS files, and legally obtained game images. USB gamepad and keyboard input are supported, while save and load states are stored on the SD card. Raspberry Pi owners who are comfortable preparing boot media and managing emulator files get a direct setup path, but the platform restriction and required BIOS files narrow its audience.
Sega CD support is the main reason to consider Mega-Pi. CUE/BIN and CHD disc-image support is paired with region-based BIOS loading, CDDA audio emulation, and RF5C164 PCM audio emulation. Those capabilities give the product a clear focus on Sega CD compatibility rather than a broad multi-system feature list. It is free, with no paid tier to weigh against the feature set. Choose Mega-Pi for a dedicated Raspberry Pi Sega CD build with SD-card save states and USB input; choose another emulator if you need support beyond Raspberry Pi or prefer a less involved installation process.
