====== 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 ====
[[https://docs.libretro.com/|RetroArch]] (formerly SSNES), is a ubiquitous frontend that can run multiple "cores", which are essentially the emulators themselves. The most common cores use the [[https://www.libretro.com/|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]'' + {{:wiki:south.png?nolink&20|South button (B SNES)}} which can be used to alter various things like [[:advanced_retroarch_settings|RetroArch and core options]], and [[:remapping_controls_per_emulator|controller mapping]]. Most RetroArch related settings can be altered from Batocera's EmulationStation.
