NEO•GEO
The NEO•GEO AES (Advanced Entertainment System) is a home console developed by SNK. It was released in 1991 and retailed for the high price of $649.99 USD. It was based on the NEO•GEO arcade hardware released a year prior. This hardware would be upgraded a few years later in the form of the NEO•GEO CD, with its ability to read disc-based media and being a lot cheaper.
NEO•GEO AES games are emulated much the same way that regular arcade games are, so the regular arcade emulators are used. It's recommended to read up on the generic arcade guide first as it will answer many questions.
This system scrapes metadata for the “neogeo” and “arcade” groups and loads the neogeo set from the currently selected theme, if available.

ROMs
Place your NEO•GEO ROMs in /userdata/roms/neogeo.
They'll also work equally as well if placed into /userdata/roms/mame, however by placing them specifically in neogeo they'll get their own little system list.
Each romset is specific to the version of MAME/FBNeo being used:
- FBNeo 1.0.0.0 romset for libretro: FBNeo
- 0.37b5 romset for the libretro: imame4all version
- 078plus romset for the libretro: mame078plus version
- 0.139 romset for the libretro: mame0139 version
- Latest romset at the release of stable for the libretro: mame/mame versions
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: neogeo.videomode, neogeo.ratio, neogeo.smooth, neogeo.shaders, neogeo.pixel_perfect, neogeo.decoration, neogeo.game_translation

MAME
MAME, the Multiple Arcade Machine Emulator, is a multi-purpose emulation framework which facilitates the emulation of vintage hardware and software. Originally targeting vintage arcade machines, MAME has since absorbed the sister-project MESS (Multi Emulator Super System) to support a wide variety of vintage computers, video game consoles and calculators as well. MAME doesn't use an individual “core” for each system like RetroArch does, instead the ROM itself usually contains the necessary information to accurately emulate it, thus making it specific to the version of MAME it was made for. Overall it's a very complicated subject, we have a guide specific to arcade just for it.
MAME configuration
MAME offers a Menu in-game (L3 + R3 or [HOTKEY] + ). This can be used to manually adjust inputs or game settings. If you're having issues with a specific game, check the MAMEdev FAQ for that game here. For MESS systems specifically, you might find more information on MESS's wiki. All options can also be edited by opening the mame.ini file.
