The emulator requires SDL.
To run the emulator, clone the repo and inside the directory:
cargo run </path/to/game>
If you want to build the source, you can run:
cargo build --release
The output binary is located at target/release/chip8_rust
The speed the emulator runs can be increased/decreased with Up/Down arrow.
Escape will quit and Space will restart
