Go Invaders

A Space Invaders emulator implemented in Go

Installation

$ go get -u github.com/danmrichards/go-invaders/cmd/go-invaders/...

Usage

In order to play Space Invaders you will need to supply the ROM files. For obvious reasons they are not included in this repo.

  -debug
        Run the emulator in debug mode
  -dir string
        Path to directory containing ROM files (default "roms")
  -scale-factor int
        Scales the original video resolution (224x256) (default 2)

Building From Source

Pre-requisites

The emulator uses the following packages which have requirements of their own before we can build with them. Follow the instructions for each:

• Pixel
• ModVendor
• Packr

Building

Clone this repo and build the binary:

$ make build

Cross compile for Windows

If you are running on Linux, it is possible to cross-compile the application for Windows.

In order to do this you will need a GCC compiler that targets Windows, such as mingw. Once installed, you can cross compile like so:

$ GOOS=windows GOARCH=${GOARCH} CGO_ENABLED=1 CC=${GCC} go build -ldflags="-s -w" -o bin/go-invaders-windows-${GOARCH}.exe ./cmd/go-invaders

Replace ${GOARCH} with your target architecture (e.g. amd64) and replace ${GCC} with the name of your Windows GCC (e.g. x86_64-w64-mingw32-gcc)
