SameBoy

SameBoy is an open source Gameboy (DMG) and Gameboy Color (CGB) emulator, written in portable C. It has a native Cocoa frontend for OS X, and an incomplete experimental SDL frontend for other operating systems. It also includes a text-based debugger with an expression evaluator.

Features

Features common to both Cocoa and SDL versions:

  • Supports Gameboy (DMG) and Gameboy Color (CGB) emulation
  • Lets you choose the model you want to emulate regardless of ROM
  • Includes open source DMG and CGB boot ROMs:
    • Complete support for (and documentation of) all game-specific palettes in the CGB boot ROM, for accurate emulation of Gameboy games on a Gameboy Color
    • Supports manual palette selection with key combinations, with 4 additional new palettes (A + B + direction)
    • Supports palette selection in a CGB game, forcing it to run in 'paletted' DMG mode, if ROM allows doing so.
    • Support for games with a non-Nintendo logo in the header
    • No long animation in the DMG boot
  • Has a text-based debugger with an expression evaluator
  • Emulates PCM_12 and PCM_34 registers
  • Emulates LCD timing effects, supporting the Demotronic trick, GBVideoPlayer and other tech demos
  • Accurate instruction and memory timings
  • Real time clock emulation

Features currently supported only with the Cocoa version:

  • Native Cocoa interface, with support for all system-wide features, such as drag-and-drop and smart titlebars
  • Retina display support, allowing a wider range of scaling factors without artifacts
  • High quality 96KHz audio
  • Battery save support
  • Save states
  • Optional frame blending
  • Several scaling algorithms (Including exclusive algorithms like OmniScale and Anti-aliased Scale2x)

Compatibility

While SameBoy passes many of blargg's test ROMs, some games fail to run correctly. SameBoy is still relatively early in its development and accuracy and compatibility will be improved.

Compilation

SameBoy requires the following tools and libraries to build:

  • clang
  • make
  • Cocoa port: OS X SDK and Xcode command line tools
  • SDL port: SDL.framework (OS X) or libsdl (Other platforms)
  • rgbds, for boot ROM compilation

SameBoy was compiled and tested on OS X and Ubuntu.
