A book that teaches how to develop games for the Game Boy and Game Boy Color using assembly language and the RGBDS toolchain.

You can read it at https://gbdev.io/gb-asm-tutorial/.

Contributing is really easy, fork this repo and edit the files in the src directory. Then, you can send your PR.

To deploy gb-asm-tutorial locally:

1. Install Rust and mdBook (v0.4.x). mdBook powers the book itself, Rust is used for some custom plugins.

$ cargo install mdbook@0.4.52

2. Within a terminal pointed at the directory book.toml is in, run mdBook commands:

# Watches the book's src directory for changes, rebuild the book, serve it on localhost:3000
#  and refresh clients for each change.
mdbook serve

# Produce a build in `book/custom/`
mdbook build
# Watch your files and trigger a build automatically whenever you modify a file.
mdbook watch

If you have Docker installed, you can pull and run the prebuilt image for this project:

docker run -p 3000:3000 \
  --mount "type=bind,source=$(pwd)/preproc,target=/code/preproc" \
  --mount "type=bind,source=$(pwd)/renderer,target=/code/renderer" \
  --mount "type=bind,source=$(pwd)/src,target=/code/src" \
  --mount "type=bind,source=$(pwd)/unbricked,target=/code/unbricked" \
  --mount "type=bind,source=$(pwd)/theme,target=/code/theme" \
  -it ghcr.io/gbdev/gb-asm-tutorial

That's it! gb-asm-tutorial is live at localhost:3000.

If you prefer to build the image yourself:

docker build -t gb-asm-tutorial .
