Changes

The [[wikipedia:Game Boy|Game Boy]] is an 8-bit, fourth-generation handheld console released by Nintendo in 1989. The original model has a monochrome display. A revision called the Game Boy Pocket was released in 1996, offering a more compact body and a better screen. In Japan, a special edition of Game Boy Pocket, called the Game Boy Light, added a front light to the screen. This feature would not be seen in Nintendo handhelds outside Japan until the Game Boy Advance SP.

==Comparison==

====Game Boy-only emulators====

* [http://bgb.bircd.org/ BGB] is a closed source emulator. It has excellent Game Boy and Game Boy Color accuracy, as well as near flawless link support. It has a wealth of options for color palettes and even enabling Super Gameboy colors and borders, though it doesn't emulate all of its functions. It also has an advanced debugger.

* [[Gambatte]] is probably the most accurate Game Boy Color emulator. It has a good range of options and features, though not quite as much as some other emulators. It's open source, but there is no activity lately.

* [[mGBA]] recently added GB/C support. It's still in development, but it's already on the level of many other emulators.

* [[GB Enhanced|GBE+]] is a recently rewritten emulator that can load custom tiles in games, including colorized tiles for Game Boy games. It also supports [[#Game Boy Features|obscure accessories]] that other emulators don't emulate.

* [[TGB Dual]] is an ancient emulator that supports link cable emulation. It supports [[Netplay]], though it requires a VPN. The libretro port supports local multiplayer using player 2's controls.

* [http://kigb.emuunlim.com/ KiGB] is an old and obsolete emulator which boasted of accuracy but was proven to be full of game-specific hacks.<ref>https://github.com/mgba-emu/mgba/issues/238</ref><ref>http://gbdev.gg8.se/wiki/articles/Test_ROMs#Emulators_running_on_desktop_computers</ref><ref>http://gbdev.gg8.se/wiki/articles/KiGB</ref> It has a wide selection of features, but there are emulators which do much better now.

====Multi-system emulators====

* [[BizHawk]] uses a modified Gambatte core. It provides speedrunning tools.

* [[Mednafen]] uses cores originally forked from an old version of [[VisualBoy Advance]] for the GB and GBC, as well as for the GBA.

==Issues==

[[File:Gbc over saturation2.png|thumb|right|350px|Comparison of saturation levels in VBA-M and Gambatte.]]

===Oversaturation===

Emulators tend to oversaturate the colors that would have been seen on the GBC's screen. This can often be fixed with emulator-specific options or [[Shaders_and_Filters#Image_Adjustment|shaders]].

==Game Boy Features==

===Hardware===

====IR Transmitter====

The Game Boy Color had an infrared transmitter and receiver. Generation II Pokémon games made use of this feature through Mystery Gift. Super Mario Bros. Deluxe could send high scores to another cartridge. GBE+ has [https://shonumi.github.io/articles/art4.html basic IR emulation] but currently it only works with Pokémon games.

====Game Boy Camera====

The latest dev builds of mGBA post 0.6.0 release can emulate the accessory by either using the PC's webcam or send a BMP, GIF, JPEG, PNG, or other image format to the game, as if it was coming from the camera itself.<ref>[https://twitter.com/mGBA_emu/status/890954205472501762]</ref> To enable the PC webcam, go to <code>Game Boy</code> under <code>settings</code> and switch the <code>camera driver</code> to <code>Qt Multimedia</code>, or by editing <code>qt.ini</code> and setting <code>cameraDriver=1</code> under <code>[General]</code>.

====Barcode Boy====

Another Japan only barcode-scanning device with the dedicated game. GBE+ [https://shonumi.github.io/articles/art6.html supports this accessory].
