A chip-8 emulator written in Go. I am trying to learn go-lang for fun and I have always been fascinated with emulators, so I decided to write one in Go. I am using the following manual as reference.

You'll need the drivers required by ebiten and you can find the relevant installation instructions here.

I wrote a blog post about this project which you can find here

- git clone http://github.com/h4ck3rk3y/go-8
- cd go-8
- go get -v -t -d ./...
- go test --cover

You can build the program by

- git clone http://github.com/h4ck3rk3y/go-8
- cd go-8
- go get -v -t -d ./...
- go build main.go cpu.go

Build the code and then

- ./main

The original chip-8 consisted of a hexa decimal gamepad. I use the following mappings.

• Your Key Board --> Chip 8
• 1 --> 1
• 2 --> 2
• 3 --> 3
• 4 --> C
• Q --> 4
• W --> 5
• E --> 6
• R --> D
• A --> 7
• S --> 8
• D --> 9
• F --> E
• Z --> A
• X --> 0
• C --> B
• V --> F

• Make roms passable as command line arguments
• Key board mapping in a configuration file
• Configurable colors
• Better unit tests for main.go. cpu.go has 98.8% coverage but overall the coverage drops significantly
