SGB-MSU1
SGB-MSU1 is a modification for emulating the Super Game Boy (SGB) that adds the functionality of the MSU-1 enhancement chip. This allows for custom, high-quality audio to be played in a Game Boy game, as it uses external PCM audio files instead of the original sound hardware. This modification is supported on devices like SD2SNES/FXPAK Pro flash carts and some MiSTer FPGA cores

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.
