Installing

The native version is published to crates.io and can be installed by running:

cargo install gameboy_opengl

Then you can run it by running: gameboy_emulator from your terminal

Building from source

The project uses Cargo as a build system, so building the project is relatively simple.

Native

cargo build --package gameboy_opengl --bin gameboy_emulator --release

this produces the executable target/release/gameboy_emulator.exe

to run it, just supply the rom file as the first file argument

Web Assembly

cargo-web is very useful for building the web port of the emulator.

cargo-web deploy --release

use your favorite static file server to serve the files generated in the target/deploy directory. You can also run cargo-web start --release, to serve the files locally.
