Euphrates is an emulator for the Sega Master System, Sega Game Gear, and Sega SG-1000 Game consoles.
It's available as a library, in the
euphrates crate. This crate,
euphrates_cli, provides a command line interface based on SDL2.
euphrates_cli, you'll need to install Rust and SDL2.
To play most Sega Master System ROMs, execute from this directory:
cargo run --release -- rom --rom PATH_TO_ROM

cargo run --release -- rom --rom PATH_TO_ROM --memory_map codemasters --tv pal
To play Game Gear games:
cargo run --release -- rom --rom PATH_TO_ROM --kind gg
To play SG-1000 games:
cargo run --release -- rom --rom PATH_TO_ROM --memory_map sg1000_2

cargo run --release --features euphrates_x64` -- rom --rom PATH_TO_ROM
You can disable debugging features (see below) as follows:
cargo run --release -- rom --rom PATH_TO_ROM --debug false
