Y.A.N.E. - Yet Another N.E.S. Emulator

Nintendo Entertainment System emulator and emulation library.

Can be used as either a standalone CLI emulator or as a ready-out-of-the-box rust crate for emulating an N.E.S.

Usage as an emulator

Download the correct release for your operating system and add it to your $PATH. If cargo's install directory is already in your $PATH, you can simply run cargo install yane.

> cargo install yane
...
> yane -h
An N.E.S. emulator.

Usage: yane [COMMAND]

Commands:
  setup      Initialize the configuration files at $HOME/.yane/
  ines       Load and run an iNES (.nes) file
  savestate  Load and run a savestate (.yane.bin) file.
  help       Print this message or the help of the given subcommand(s)

Options:
  -h, --help     Print help
  -V, --version  Print version
> yane ines path/to/my/rom.nes --muted --debug --keymap-file=my/custom/keymap.yaml

See KeyMap for the default key bindings.

Running yane setup will create a bunch of configuration files at $HOME/.yane. These can then be edited to change the keymappings, settings, logging directory, etc. Yane will check for these files before running every time and fall back on the defaults if they don't exist, so you can run the emulator without running yane setup if you want.

Usage as a library

// Load an iNes (.ines) file
let ines = include_bytes!("./my_game.nes");
// Create a new N.E.S. console with the game inserted
let mut nes = Nes::with_cartridge(Cartridge::from_bytes(ines, None));
let config = Config::default();
// Advance the N.E.S. by 1 frame (i.e. until the VBlank interval)
nes.advance_frame(&config);
// Reset the N.E.S.
nes.reset();

See the documentation on the library portion or the examples folder for more.

Feature Flags

Yane includes one feature flag, sdl, which is enabled by default. It includes the SDL interface that comes with Yane (i.e. everything in yane::app). If you want to use yane as a pure rust library, you can omit this flag.
