Nintendo Game Boy
The Game Boy (GB) is a 8-bit, fourth-generation handheld console released by Nintendo on July 31, 1989 and retailed for $89.95. The Game Boy has a Sharp LR35902 core CPU at 4.19 MHz. It had a monochrome display that could only show four shades of grey, albeit with a olive green tinge on the original. It's successor is the Game Boy Color released in 1998.
This system scrapes metadata for the “gb” group(s) and loads the gb set from the currently selected theme, if available.

BIOS
No Game Boy emulator in Batocera needs a BIOS file to run.
If you'd like to use a BIOS for instance to see the game boot animation:
| MD5 checksum | Share file path | Description |
|---|---|---|
32fbbd84168d3482956eb3c5051637f5 | bios/gb_bios.bin | Game Boy BIOS |
ROMs
Place your Game Boy ROMs in /userdata/roms/gb.
To play Game Boy games in their Super Game Boy mode, place your ROMs into the roms/sgb folder.
To play two virtually linked Game Boy instances for multiplayer games, refer to GB2Players.
Emulators
RetroArch
RetroArch (formerly SSNES), is a ubiquitous frontend that can run multiple “cores”, which are essentially the emulators themselves. The most common cores use the libretro API, so that's why cores run in RetroArch in Batocera are referred to as “libretro/(core name)”. RetroArch aims to unify the feature set of all libretro cores and offer a universal, familiar interface independent of platform.
RetroArch configuration
RetroArch offers a Quick Menu accessed by pressing [HOTKEY] + 
which can be used to alter various things like RetroArch and core options, and controller mapping. Most RetroArch related settings can be altered from Batocera's EmulationStation.
Standardized features available to all libretro cores: gb.videomode, gb.ratio, gb.smooth, gb.shaders, gb.pixel_perfect, gb.decoration, gb.game_translation

libretro: Gambatte
Gambatte is an accuracy-focused, open-source, cross-platform Game Boy Color emulator written in C++. It is based on hundreds of corner case hardware tests, as well as previous documentation and reverse engineering efforts. The accuracy of the emulator is among the highest and is based off numerous reverse engineering tests and document studies.
We use the latest libretro core. See the official documentation for more information.

libretro: Mesen-S
Technically a SNES emulator, Mesen-S supports Game Boy via the Super Game Boy (or at least, an emulated version of it). Requires the appropriate BIOS files to function.
ROMs placed in the roms/sgb folder will appear in the SNES's game list, opening them from here will start the Game Boy game as if though you were playing it from the Super Game Boy. How neat!
