Gearboy is a Nintendo Game Boy / Game Boy Color emulator written in C++.
The emulator is focused on readability of source code, but nevertheless it has good compatibility.
A lot of effort has gone into this in order to follow OOP and keep it as simple as possible.
Here is list of latest changes:
+ fixes window glitches with many games
+ fixed a bug resetting DIV register
+ sound filters adjusted for maximum resemblance to dmg
+ increased ghosting effect
+ improved MBC3 overall performance
BGB is a GameBoy, GameBoy Color, and Super Gameboy emulator/debugger which runs on Windows. Program features accurate emulation of the hardware, powerful debugger, SGB multiplayer with up to 4 gamepads and TCP/IP game link support, graphics with GDI, DirectDraw, Direct3D, OpenGL output, and HQ2X, Scale2x, scanlines, blocky filter, accurate/high quality sound emulation, bandlimited synthesis, GameGenie and GameShark cheat, and more.
fixed time keeping problems (hiccups) on windows 7. fixed inaccuracy in mid-scanline change of LCDC bits (gejmboj). fixed a condition that would cause inaccurate timing of interrupt (final fantasy adventure). added "gameboy or GBC" system mode setting. added "blurry" doubler. fixed searching any opcode with a space giving "IO error 105". added field in IO map to view/edit the "low" bank of multicart emulation. fixed "remotejoy" bring broken. screen window can now init on secondary monitor. fixed failure of GUI elements initing on secondary monitor. fixed wrong field in wav file written.

GameBoy Online is a Game Boy and GameBoy Color emulator written in Javascript. It strives to be efficient and try to have a perfect compatibility. Currently the execution speed is not optimal even on browsers. For example on Chrome, which is nevertheless deemed to run Javascript faster on a PC running Windows 7 64-bit version with a double heart 2 CPUs at 2.2 GHz, games run at normal speed but almost skipping some frames.
The sound production is still experimental and rather poor quality. The video portion is by HTML5 or by creating images with BMP string URI. State backups are implemented using the object window.localStorage and are serialized / deserialized JSON. Ditto for backup SRAM.
Recent Changes:
- Emulating an undocumented behavior: HDMA becomes GDMA when LCD is disabled. This fixes Worms Armageddon. Manual disassembly + Firebug = :3
- Optimized the DMA code by inlining whole tile block loads. Kirby Tilt N Tumble can now boot, I will get the special gyro implementation landed soon, since it is running as an MBC type 5 cartridge for now.
- Updated Updating the midscanline working pixel determinism.
- Updated LYthe LY register reset write case handling.

Recent Changes:
- Worked around a problem of incorrect timing of setInterval in Google Chrome JavaScript engine V8.
- Update the algorithm automatically jump frame.
- Remove mozBeforePaint as Mozilla miscalculates the maximum rate of frames per second supported on newer operating systems.
- Changing the timing of the internal loop of the interpreter to 17ms 16ms.
- Added library support swfobject 2.2 for Internet Explorer.
- Update the default color of the background when it is cut and the boot ROM is disabled and the emulator is not in CGB.
- Remove unused characters in the code.
- Fixed a regression in the opcode ADC A, A '.
- Small update of the HALT opcode.
- Ensuring that the way the special case of the HDMA HALT is taken into account instead of the normal path when necessary.

fixed: a sprite on X = 0 uses more time in mode 3, too.
fixed: inconsistent timing if resetting in the debugger.

Nintendo Game Boy Emulator in C# using SlimDX, written in 2011 by xdaniel
Downloads: SharpBoy v0.1 (32-bit binary)
Default controls:
B: A
A: S
Start: Return
Select: Space
D-Pad: Cursor keys
Notes and bugs:
Emulation is still incomplete and has bugs, especially with GBC games
No sound, serial link, SGB, etc. for now
No documentation yet either; controls cannot be changed from within the program (edit config.xml manually after first run)
GUI has some quirks (ex. window resizing), FPS limit and counter arenīt accurate
Debugger slows down emulation speed considerably, needs some serious optimization
Probably more...
...and despite this, thereīs a bunch of playable games:
A new version of the Game Boy emulator zBoy has been released.
