## What it is
GoBoy is a multi-platform Nintendo Game Boy and Game Boy Color emulator written in Go, with colour and sound support. It was built primarily as a development exercise and includes debugging features like opcode tracing and sound channel toggling.

## Use cases
- play gameboy roms on my computer
- emulate game boy color games on mac
- learn how a gameboy emulator works
- step through cpu opcodes of a gameboy emulator
- run zelda.gb from the command line

## When to choose
- you want to play most Game Boy (and some Game Boy Color) games on macOS, Windows, or Linux
- you want to study or contribute to an emulator written in Go
- you need debugging aids like opcode printing and step-through execution

## When to avoid
- you need high-accuracy emulation of all Game Boy Color games
- you want save states, netplay, or other modern emulator features
- you need a actively developed emulator rather than a work-in-progress project
