Available frontends:

FAQ

Backend?

This module will emulate the hardware of the Gameboy Color.

You can write a 'frontend' to receive the screen data and render it to a medium of your choosing, along with handling keyboard inputs, and something to handle saving battery saves.

See the _examples directory for a simple example of how to write a frontend. Alternatively, look at the 'Available frontends' above.

Features?

• ⚠️ Mostly works. It is not a perfect emulator by any means and some games might not function correctly.
  • ✅ blargg CPU tests pass
  • ✅ blargg memory timing tests pass
• ✅ Supports battery saves for ROMS that allow you to save state
• ❌ Audio is NOT implemented right now
• ⚠️ Does not support RTC clock on MBC3 (although games can still be played)

How do I build it?

This is a 'library' module, no build required.
