GoGB

GoGB is a work-in-progress of a Gameboy emulator written in Go. The main objectives for this project are:

• build a medium-large sized project in Go to become familiar with the language and the design patterns associated with it.
• write an emulator that is performant enough to run Super Mario Land at a playable frame-rate.
• I am not planning on implementing sound for now.

Build Instructions

git clone https://github.com/guigzzz/GoGB
cd GoGB && go build
./GoGB <path to rom>

Controls

• up, left, down, right = w, a, s, d
• A, B = j, k
• start, select = u, i

Todo

• create unit test suite for backend
  • instructions: arithmetic
  • instructions: memory
  • instructions: rotates
  • instructions: shifts
  • instructions: miscellaneous
  • CPU base
• implement basic graphics to be able to run test suite
  • learn how to draw graphics in Go + basic implementation
  • implement draw background
  • implement draw sprites
  • implement draw Window
• Advanced tests: get the backend to pass correctness and timing tests
  • Run blargg tests as a standard go test
  • Automatically run blargg tests on commit
• Robust graphics implementation
  • Tetris playable
  • Super Mario Land playable
