Another Game Boy emulator written in Zig, for fun. At least that's the plan.

BoyZ II Game

Another Game Boy emulator written in Zig, for fun.

At least that's the plan.

Why the name?

• Zig, Game Boy
• Boy (Zig) Game
• Boy(Z II G)ame

It's a play on "Boyz II Men", the name of an R&B group I know mainly for their hits from the 90s, which were on the radio around the same time I would spend countless hours on my Game Boy.

Dependencies

• Tested with zig 0.11.x
• raylib is expected to be installed as a system dependency.
• A boot ROM is required to be downloaded manually to src/dmg_boot.bin
  • Tests expect to use the standard DMG boot ROM
  • For other purposes you can use something open source like the ones SameBoy uses. You can download SameBoy and find pre-built boot ROMs in its application folder.

OSX

brew install --HEAD zig # verify that this installs zig 0.11.x
brew install raylib # only tested with 4.5.0
