A Gameboy Color Emulator written in Rust

You can clone this repository and build it using either the make command or cargo build --release --features=gui. Running the emulator can be done either via cargo run --release --features=gui, or by running the generated binary found in target/release. You can copy the executable named rboy or rboy.exe to some sort of binary directory such as ~/.local/bin/ in linux or something under the PATH in windows.

Then you can explore the ability of the emulator by rboy --help. Which outputs
