Inputs: // inputs can be updated through the JoypadState array Getting the backbuffer: // this returns a BGRA encoded byte of the full 160x144 GB displayīyte backbuffer = emulator.GetScreenBuffer() and you can use GBZ80.ClockSpeed to synchronize the emulation speed it returns the number of CPU cycles that have been used DecodeAndDispatch emulates the next CPU instruction Using (BinaryReader br = new BinaryReader(fs))Įxecuting the emulation: // better to run this from a thread Using (FileStream fs = new FileStream('MyRomFile.gb', FileMode.Open)) Initializing and loading a ROM: GBZ80 emulator = new GBZ80() Here are some code snippet to get started with LeBoyLib. You can build it and use it in any kind of C# project.

LeBoyLib is the main emulation library and is independent of MonoGame. Make sure that you are either using the latest development build installer or building MonoGame from sources ( develop branch). LeBoy requires a bleeding edge version of MonoGame.

Refactoring the LCD controller emulation to be less hacky and faster.

Refactoring GBMemory and optimize memory read/write to enhance performance.

The flexibility of emulators has given rise to some software which can be played on it. For example, for the Mac users, not many games are available for the Mac OS, but, with the use of an emulator, a lot many games can be played on Mac.

OAM priority and read/write: OAM emulation is not quite accurate yet, some sprites have wrong priorities and this may result in sprites not displaying, or being displayed above/under other elements. An emulator is used when the need arises to use particular hardware to play software meant for other hardware.

Some Memory Bank Controllers (MBCs): only MBC1, MBC2, MBC3, and MC5 are supported (without RTC support).

GBC & SGB: only the base GB (DMG) is fully supported.Real time clock (RTC): clock support is absent and queries to clock registers will return 0.Sound: it currently doesn't generate sound.LeBoy is not meant for accuracy and speed, it is a pet project which initially started for educational purposes. The core emulation library ( LeBoyLib) is a separated pure C# project that can easily be embedded into any kind of C# project. It is designed to be cross-platform (currently supporting Windows, MacOS, and Linux, but should already run as-is on iOS, Android, and consoles). LeBoy is a GB emulator written in C# and using MonoGame as a graphical and sound output. Disclaimer: GAME BOY is a trademark of Nintendo Co., Ltd.
