===Comparison===

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

;[[SameBoy]]:A relatively new emulator, probably the most accurate Game Boy emulator currently. The UI is simple and easy to use. It includes open source bootroms, although these can be replaced with real ones. Also emulates Game Boy Camera and Game Boy Printer.

;[[BGB]]:A closed-source emulator for Windows (and [[Wine]]) with 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 Game Boy colors and borders, though it doesn't emulate all of its functions. It also has an advanced debugger.

;[[Gambatte]]:Extremely accurate open-source Game Boy/Color emulator. It has a good range of options and features, though not quite as much as some other emulators. It has not been as active lately.

;[[TGB Dual]]:An ancient emulator that supports link cable emulation. It also supports [[netplay]], but it requires a VPN. The libretro port supports local multiplayer using player 2's controls.

;[[KiGB]]:An old and obsolete emulator which boasted its 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 other emulators have caught up and are already doing much better.

;[https://github.com/AntonioND/giibiiadvance GiiBiiAdvance]:Pioneered full GB Camera emulation, including webcam support. Aside from that, it's an unfinished emulator with the basics set up, but its promising future currently on hiatus. It has very accurate timing.

;[https://github.com/aappleby/MetroBoy MetroBoy]:Extremely accurate Game Boy simulator which being written in a subset of C++ that's designed to to be mechanically translated into Verilog HDL.

==Emulation issues==

===Oversaturation===

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

====Emulator options====

'''mGBA:''' Under Tools > Settings > Shaders, you will find three customizable '''Desaturation''' parameters.

'''VBA-M:''' Under Options > Game Boy, you will find the '''GB color option'''. The recent nightly builds also include the '''LCD Filter''' option.

Much like the NES, the Game Boy (and by extension, the Game Boy Color) used '''Memory Bank Controllers''' (MBC) (called MMCs on the NES) and also known informally as '''mappers''', to go beyond the restrictive initial hardware specifications. Nevertheless, Nintendo was much more careful to standardize their specifications to just a small number of possible mappers. Moreover, Game Boy ROMs now included an official internal header mandated by Nintendo that included the correct MMC type. This meant that for the officially licensed games, these mappers proved to be rarely a problem... with some notable unimplemented exceptions: Net de Get's MBC6 that offered downloadable content off the internet, and the MMM01 footer used for some official multi-cart games, among others.

However, shit hits the fan when it comes to '''unlicensed games''', since they didn't necessarily respect Nintendo's specifications about how a given mapper type should handle its memory and behave in general, and internal headers were often filled with erroneous data to hinder dumping and emulation efforts. Some emulators like MESS and [http://hhug.me/?tags=hhugboy hhugboy] try to emulate that behavior with various degrees of success ([http://hhug.me/dump/ Compatibility List]). The hhugboy project also proposed a similar solution to iNES for this mapper problem, as the [http://hhug.me/gbx/1.0 gbx ROM format] that appends a footer with extra information needed for some unlicensed games. However, this format, much less unlicensed hardware quirks, isn't widely adopted aside from tentative mGBA support.

===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+ had [https://shonumi.github.io/articles/art4.html basic IR emulation] back in July 2016 but it then only worked with Pokémon games. Now, as of [https://shonumi.github.io/articles/art11.html April 2018], it has full IR emulation for most IR-enabled games (Hudson Soft's HuC-1's IR capabilities need to be emulated for Japanese ''Pokémon TCG'').

The Game Boy Camera is an official Nintendo accessory for the Game Boy and was released in 1998. Users can take pictures and modify them with stickers and frames, as well as play several included minigames. In addition to the original model, there was a US-exclusive Legend of Zelda: Ocarina of Time edition that included different stamps.

===Motion Control (Tilt Sensor)===

===Rumble===

* '''4-Player Adapter:''' Currently only [[GBE+]] supports it. There is a 16-Player adapter as well, but it went unreleased outside of unused code in some games, and as such isn't emulated.

====Mobile Game Boy Adapter====

There is a Japan-only accessory that communicates with Mobile Golf and Japanese Pokémon Crystal. It was bundled with Mobile Trainer cartridge which allowed the player to use e-mail as well as browse Nintendo's website. It saw use on some Game Boy Color and Game Boy Advance games, but support was limited to Japan, and the servers went offline by 2002.
