# 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](https://github.com/LIJI32/GBVisualizer)
|
||
|
|
* Emulates LCD timing effects, supporting the Demotronic trick, [GBVideoPlayer](https://github.com/LIJI32/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
|
||

|
## Compatibility
|
||
|
|
While SameBoy passes many of [blargg's test ROMs](http://gbdev.gg8.se/wiki/articles/Test_ROMs#Blargg.27s_tests), 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](https://github.com/bentley/rgbds/releases/), for boot ROM compilation
|
||
|
|
|
||
|
|
SameBoy was compiled and tested on OS X and Ubuntu.
