EmilDrive is a Sega emulator written from scratch in Rust, running on macOS, Linux, Windows and Android. It covers the Mega Drive / Genesis, Mega CD / Sega CD, 32X and Master System, with save states that persist between sessions, paced rewind, cheat codes, ghost challenges with a map of where you've been, sound recording, and two-player support on keyboard, controllers or touch.
You point it at games you already own (local folders or SFTP, FTP and SMB servers on your own network) and nothing is ever downloaded.
Compatibility over 98% and multi-platform.
